None of the economic problems we have are inevitable. They have not come about through forces of nature. The fact that less than a dozen people own more wealth than half the population of the earth is not something that happened through some irreversible, irresistible natural process. This has occurred through deliberate, calculated, relentless effort by corporations and the rich to create legislation and investor rights agreements over the course of decades.
America had a president, Franklin Roosevelt, who was easily the most popular president in the nation’s history (he kept being re-elected until he died), who actually proposed imposing a maximum income in the United States. He succeeded in imposing a 94% tax on the very rich, and ushered in the greatest period of economic growth the country had ever seen. That wasn’t so long ago.
There is no reason why these things cannot be changed.
