The wealthy have the resources and access to professionals not to pay tax. So they don’t.

I agree that they should pay tax, but they don’t. It is how it is.

There are two main things that seem to work:

1. Having taxes at low levels for everyone generally.
2. After a two or sometimes three generations, the wealth is frittered away by overindulged great-great-grandchildren. Sometimes they are so wealthy, well-educated and taught to wealth preserve that that doesn’t happen.
