And of course, you could have inheritance tax so that after a few generations, there is nothing left in the hands of the original descendants.
Wealth should be kept in secret and only the wealth you need to spend in front of the society should be declared as income at the spot. Why? Because there is no way to enforce the opposite. Laws that cannot be enforced reliably should not exist at all. I'm pretty god damn sure the Rothchilds family won't pay shit to the government as inheritance taxes. Why should average Joes do that if the elites do not?
The fact that we have inflationary monetary system is simply to keep the poor in poverty. The poor will have to constantly beg for higher wages as inflation eats their income year after year. If the system was deflationary then wages should be lowered periodically and the employers (high-rank slaves) would become those beggars. Deflation flips the pyramid upside down. In my opinion, that's the main reason why deflationary monetary system is propagated as the greater evil. The latter, of course, is a conspiracy.
