"But the things people with money try to buy, education, property, financial assets, are mostly of a fixed supply and the prices will just keep spiraling."
Education is not in any way a fixed supply. We can train more teachers.
It's not fixed, but it's not perfectly elastic either the way, say, hot dogs are. Part of the value of educational institutions is their track record, new schools have no track record, so aren't a perfect substitution.
