The advertisers (and magazines) have a right to make a parnassah just like you do.
How rich people choose to spend their money is up to them. For all you know the guy with the $40,000 watch needs it to impress hotshot clients and along with the $40,000 he spent on the watch he also donated $400,000 to cover the tuition that you don’t pay because you are too busy ranting in the coffee room about how rich people spend their money and therefore have no time to work.
