Which is beside the point. The point is that the entire 100 million belongs to the man who EARNED it, not the government.
— and probably enough for many successive generations.
It is entirely his right to pass along his wealth to his heirs.
But they are frightened about losing the other $90 million even though some of their compatriots are homeless.
First, they are not frightened about losing the other 90 million. They are frightened that a government that can take 90 percent of their earnings can just as easily take ALL of it. Second, the poor "homeless" people are not their compatriots. THE rich man is not homeless. He has made decisions that resulted in him making 100 million dollars. The others have made decisions that have resulted in their being homeless. The only thing they have in common is that they're all human beings. The rich man owes the homeless man nothing.
As I read this, the author assumes $100M in income and a 90% tax rate. This yields $90M for the government that year with $10M remaining to the earner. The author then makes a statement about the earner being frightened about losing the other $90 million he wants to keep. But the earner has only $10M left.
The author has made at least an $80M error in his calculations here. Perhaps it is because on his overpowering sense of jealousy and envy that he cannot do simple math.
