There are a load of 'millionaires' that are still busy keeping their company going/growing, which is where their money comes from. The people like Bill Gate - the billionaires many times over - they have the luxury of time to decide what to do, and the money to make it happen. No doubt there are many millionaires with the luxury of free time, but probably not as many as you think. Meaning, if they stopped doing what they're doing, the money would mostly go away pretty quickly.
