When you live that lifestyle you learn to spend it. A friend of mind used to rent an apartment to someone making $40k/month - the renter was often late paying her monthly $500 rent because she was out of money until next payday (the apartment was a third home used only to visit her kid who was going to school nearby). When you can afford to buy any neat car you see after a while it no longer occurs to you that maybe you shouldn't buy it anyway.
