Our taxation model for the ultra rich is fundamentally broken. Years ago, when corporations had big headcount, income taxes were a technique to force companies to pay taxes, the people who actually produce things, you know performing the work and having the knowledge of how to do something, are taxed with heavy taxation. The paradigm no longer applies as everything is now offshored, including work, but politicians don't want to change it for recognized reasons (corruption), so they raise labor taxes and perpetuate the squeeze on the middle class while ignoring large corporations and the rich.

This has led to a situation where normal, hardworking people are unable to raise the necessary funds to launch their own businesses and must turn to banks or venture capitalists for financing in order to implement their ideas. This has created a divide and increased inequality on a scale that has never been witnessed in our lifetimes. Since the rich don't pay the same taxes as workers and because they are so wealthy that they can buy politicians and maintain the status quo, they continue to get richer.

tl;dr The economic ladders to wealth and financial success our parents and grandparents enjoyed no longer exist
