You just don't seem to get simple concepts. In both examples the rich guy has the same amount. But one example there is lots of inequality and in the other there is less. The restaurant does better with less inequality for obvious reasons.
Only if we lived in a country that liberals made up.
In our country, it doesn't matter how much other people have, that's why income inequity is meaningless. If the millionaire goes to that restaurant, and reads the paper finding out he lost a lot of money to the point he's no longer a millionaire, then how does that help the restaurant?
It doesn't because no matter how much he has, made, or lost, it doesn't bring anymore people into the restaurant. It didn't in the past and it won't in the future.
So forget the millionaire, and let's say the government lowered taxes on middle-class people, cut our social programs so only those who have no choice be on them, closed the borders so nobody legal or illegal gets in, deported all the illegals we have now, and people were forced to work or die, that's when the restaurant would see more customers.
Again, income inequity is based on the failed concept that we live in a bubble, and in our bubble there is only so much money. The reason some have too little is because in our bubble, others have too much. That's nothing but a lie. Money is nearly endless in our country, and anybody can make money here. Nobody was ever denied a raise from their employer, a loan from the bank, or profit from an investment because the rich people have too much money. It's never happened.
