Wealth does not get sucked into a black hole.
Wealth can be sucked into a black hole particularly when it is heavily taxed, socialised or nationalised. Just look at how the soviet union collapsed and its industrial base was left to rot and decay. That's wealth destruction. A lot of wonderful estates in France r being sold off cause the owners can no longer afford to pay the, literally, wealth tax. That's also wealth destruction.
On the free market, individuals and private enterprises generate wealth and the state merely destroys it.
This is crucial. If u don't get this u might as well go back read ur Economics 101.
The super rich will go down and wealth will flow more back into the hands of people who create wealth rather than speculate on wealth.
Bar a bloody revolution, the super rich are too smart to go down. If they r not smart enough, they hire the smartest people around to make sure they don't go down.
I am a big believer in the free market, both for charity and for correcting the problems of economics, including the lack of a middle class
You seem to be a "picky" believer in the Free Market. You shouldn't. Free Market is basically guaranteed property rights and the freedom to engage in exchange of goods and services. No more and no less. It doesn't crash the poor, it doesn't favour the rich, nor does it decimate the middle class. All these woes are the direct result of government meddling, coercion and theft.
