Will they actually though?
You hear a lot of anecdotes both ways and it is quite hard to get a good picture of the real situation.
Keep a weather eye out with that line of scepticism. One of the opinions down that path is that MIT should adjust its admission procedures to filter out the children of honest businesspersons.
One hypothesis for why you see both anecdotes is that the IRS is extremely good at filtering out these cases… when they bother to look into it. A lot probably get by without ever being audited, but the small percentage that do regret it.
