If all the money ends up in hands of billionaires and their corporations and there will be no money in hands of regular plebs…
Who do you think will have to pay the taxes?
Also, the people would figure out a different way of trading or currency. And with that one getting taxed, all the billionaire’s money become worthless.
That is an ongoing process, but it looks much different from what you imagine. Even now, a large part of the economy is working for the top 10 percent, producing luxury goods and services. Wealthy customers provide the biggest margins for companies.
“Regular” customers are getting more irrelevant every day. There was a time when your role as a consumer was important for the economy. This role gave you power and influence because companies were competing for your money. This era is slowly coming to an end, something most people haven’t realized yet.
Rich people can be fools, and a fool and his money are soon parted. That’s why much of the economy is just everyone trying to scam everyone else.
