I agree with you on the 1920s, but you can add the 1890s, and 1980s in that mix.
This is about what it has always been about.
Filthy rich oligarchs, and bankers, corrupting the entire system through business monopoly, and bribing politicians, and judges.
Until that is addressed, nothing will change.
FDR went a long way towards addressing, and fixing that very problem, and was popularly elected four times, because of it.
This led to the largest peace, and prosperity in the country's history between 1945-1980. Then it all fell apart when the oligarchs, and bankers got their guy in office.
If you really are a former teacher, then that means you deal in facts. And the fact is, Republicans mostly, and a few Democrats, want to end our experiment in Democracy, and install another King George III government, for their own wealth and power, backed by the filthy rich who do not want to participate.
It's just that simple, and every American is going to have to decide which side they're on. Working class America, or the bankers.
