In a word: EDUCATION
Specifically, truly live up to America's capitalistic ideals. If free market capitalism is what this country is truly all about, then the way to truly turn things around is to teach the nation's people about the world of finance. I'm not talking about a basic economics class. I'm talking about a complete course study OR perhaps aspects of financial literacy could be taught from elementary school through high school. Our public education system got away from doing this even in high school several years ago. The idea is finally making a revival which is a good thing. But if you want to change things and get away from this "US -vs- THEM", rich -vs- poor issue, the best way to do it is to education your nation's people about money! For too long this has been left up to individual households to do. Unfortunately, not all "heads of household" have a true understanding about finances. You'd be surprised, for example, to know how many millennials really don't know how to balance a checkbook. (Of course, to be honest most of us who are one generation above rely on spreadsheets and calculating apps to "do the math" for us. So...:shrug
Now, there will always be some people who won't get the lesson. And these people will struggle financially. Moreover, there will always be poor people among any society. That's a given. Additionally, I fully understand that there will be people on both ends of the financial spectrum who will be irresponsibly with their money, but I'm of the opinion that the more you teach people about the world of finance even on a basic level, the more responsible financial stewards you'll have. And most of those will go on to be savers and investors, not spend thrifts.
From there anything is possible. For example, if you want to go on to take more advanced courses in finance, i.e., become a CPA, you can do that. But you'd have the basics in financial literacy down beforehand. To me, that's a good thing.
