This is the biggest problem in American politics.
For 50 years, corporate profits averaged roughly 7% of national income. Today, corporate profits account for more than 14%.
In today’s dollars, that difference is about $2 trillion per year.
There is no single explanation for why this shift occurred, and it certainly isn’t just one thing.
This isn’t all bad either. A larger corporate profit share helps explain why corporate earnings and asset prices have risen so strongly relative to the economy and to history, benefiting many people.
But the distributional effects of this shift are substantial, and they help explain why so many people feel the current system isn’t working for them.
This trend has been developing for nearly 30 years and spans political parties.
