They did pay 40% before the trump tax cuts.
I do not overestimate the amount of American that are invested. Most people are not going to invest if their employer doesn't set it up for them. That leaves a lot of people out especially the restaurant industry. You'll find in my earlier posts I issues with the low financial literacy in this country. To me this is an education problem. How much bullshit do kids learn in high school but they don't teach basic financial literacy (actually many are starting which is great but i didn't have anything like that in school) . Why aren't we educating people of the importance of balancing a budget, living within your means, saving for retirement at a young age, staying out of debt, the benefits of owning vs renting, driving a used car rather than having an expensive car payment. These are keys to pulling yourself out of a financial pit. I learned all about this stuff in prison when I should have learned it in school. I've done very well since I've been out and I credit those classes for a lot of it.
