IT and Programming have a booming job market and salaries are, on the high end, virtually unrivaled by other industries, save for things like Doctors or high-end Lawyers. And unlike Lw and Medicine, a B.S. from a decent school (plus some hustle) is enough to get in to a FAANG.
Eventually the industry is going to cool, but for now Tech really is the closest thing to that Steinbeck quote about temporarily embarrassed millionaires.
