Economists don't necessarily understand everything that's going on. So if you want to ask, why did inequality take off? The answer is, that's an interesting question. We have a bunch of stories-- there are-- there's probably some truth in all of them. Some of it is probably technology. It's probably true that technology reduced the demand for regular laborers, increased the demand for people with lots of formal education. Although, even college graduates haven't done so well since about 2000. Another answer-- a little bit is globalization. Certainly, some significant number of blue collar jobs were lost-- imports from China, and that sort of thing. A lot of it, though, seems to be changes in institutions and social norms. Why do I say that it's cultural and not economic, or not purely the underlying economic story? We can, to some extent, measure the impacts of things like technology and trade. And they're not enough. They're not big enough to explain what we're seeing, you know, and-- which says, well, it's got to be something else. And cultural and political shifts are a natural place to look. Part of it is timing-- this big turn corresponds pretty closely to the election of Ronald Reagan, right? You can see that that's happening. Partly, it's history. We know that this great compression-- that was clearly political. So if the great move towards equality was political, then it's a pretty good bet that the significant part of the movement back towards inequality is also political. Got to say, all of this is a little bit of, you know, we're doing a fair bit of hand waving. But, sometimes, if that's where things seem to point, you say, look, this looks to me like it's not-- for once, it's not just supply and demand and the invisible hand. That there's something going on about social norms and politics. Used to be that when corporations were deciding on the CEO's paycheck, right? Who decides how much a CEO is paid? Well, there's a compensation committee. Who appoints the compensation committee? Actually, the CEO appoints the compensation committee. So you might say, well, of course, they're always going to vote gigantic paychecks for CEOs. In fact, they used to be inhibited about that. They used to say, well, let's-- we can't, you know-- it'll hurt worker morale if we pay this CEO too much money. And the union will protest. But these days, unions have been vastly reduced in influence. The notion that-- you know, the norm that says that outlandish pay to the CEO while the workers are poorly paid kind of went away. And a lot of that probably comes back to politics. The decline of unions-- a lot of that decline took place during the Reagan years because Reagan administration had strongly anti-union policies. And so on, down the line. So it looks like there's kind of a turning point politically, institutionally, around 1980 that turns us into this highly unequal society. And it hasn't fully played out yet. That's, am...

Think like an economist

For Nobel Prize-winner Paul Krugman, economics is not a set of answers—it’s a way of understanding the world. In his economics MasterClass, Paul teaches you the principles that shape political and social issues, including access to health care, the tax debate, globalization, and political polarization. Heighten your ability to read between the lines and decipher the underlying economics at play.


Students give MasterClass an average rating of 4.7 out of 5 stars.

the course should be more accurately named US Economics and Society, but still a pleasure

Krugman rocks! (I realize that's not terribly helpful, but the course was so rich in information and philosophy that I can think of no way to sum up the whole experience except to acknowledge that it was overwhelmingly positive.)

A nice overview of society and economics with recent examples explained in a clear way.

Very clear, concise and inspiring. He's a great teacher and taught me to think critically regarding economic issues. 10/10!

I can easily see why him and his Masterclass divide so many opinions. It's very hard to dissociate politics from opinion, but it's amazing how this has helped me understand the world around me, specially since I am a budding enterpreneur from Brazil, which is notably a country plagued by unthinkable amounts of inequality and incredibly polarized politics.

This series with Paul Krugman almost got me to cancel and never return to Masterclass.

This is suppose to be a "class" but all I hear is opinion and opinion and opinion filled in with more opinionated commentary. As an economic professional why doesn't he mention how much it would cost and where the money would come from. Why do I always have to hear someones political views and why can't I ever just hear some facts and evidence. This ruined the whole masterclass for me

I think part of this was more political. Inequality is inherent and co-relation doesn't mean causation. However, what it does suggest is by fixing inequality through standard programs, there can be a safe assumption based on the past that that would lower political dispute. However, it's also essential to ask if doing so would be worth the purchase- what would be the opportunity cost?


Interesting! In the past, technology development force many industry workers out of work but also create new job opportunities. With more and more jobs to be replaced by robots, it seems to me that job opportunities will be fewer than people looking for jobs. Will the development of technology such as AI create more inequality?

First time I have seen a real answer to the why the Bipolar of Politics is getting less gray and more Black and white. The correlation tells a whole lot. Well said in just under 15 minutes.

If the federal government (electoral college) overrides the voting system of the presidential collection, it also controls the rest of the government system. We need more conscientious, mindful and altruistic politicians and policy makers in congress, senate and electoral college.

Economics, politics and psychology will always be inextricably coupled. If you ignore this coupling you cannot produce useful analysis. It is, however, better to express issues like inequality in more pragmatic terms. There is absolutely nothing wrong with creation of considerable wealth but we have to remember that significant success is built on the foundation of healthy, educated, stable society and those who have had great success owe a considerable debt to the nation. Right now the support of the foundation is considerably out of balance and this has put an enormous pressure on the middle class. Using a “pragmatic” perspective consider healthcare. Yes universal healthcare is a moral issue but having a functional national system also provides the competitive advantage of a mobile, agile workforce (and innovation community) that most of the rest of the world has. Yes ideology is a destructive force in our current national dialog but the answer is more scientific (problem-solving), pragmatic thinking. We need to have the numbers and data to back any argument and Dr. Krugman is attempting to supply this. Failing to supply this information leaves economics in a vacuum.

Basic economic principles are great! Agenda driven Ideology... not so much! Stick to the topic!

From Trust Busting during Teddy Roosevelt's time to Franklin Roosevelt's New Deal, Public Policy always effects the economy. Given that Boomers are the most selfish, entitled and narcissistic class in America at the moment, I'm not the slightest bit surprised that they won't want progressive policies toward expanding the middle class. Unfortunately, it's my belief that the Boomers will have to pass on before America can resume looking toward a healthy country with a broad middle class. Once on the road to recovery, first and foremost, education in this country must dramatically expand with less expensive education at all levels. At this frightening moment in history, ignorance seems to be fueling the elected class. And even a prospering country as a whole cannot withstand the current amount of ignorance without long term consequences. America was based on the concept of a Jeffersonian Democratic population and must return to those ideals with all deliberate speed.
