I set up a C-Corp at one time — to qualify on a bid as a subcontractor on a contract to IBM for replacing computer systems for a toll bridge commission. Otherwise I never really used it.
If I was a Section 8 minority — a black woman with a Hispanic surname, say — I would have definitely used a corporate structure. Then I would have done very well in the railroad business, at the least.
Also see my post a few minutes ago about Stark’s screed.
One of my vendors on the railroad project set up a C corp in his wife's name. He is Indian and makes multiple trips to India each year to work with friends and associates. He was formerly a co-worker at my current company.
