I did some work for a company. The old man started off with a dump truck and turned it into a huge profitable company. Now into all sorts of things - development, real estate, mining, etc.
The son and daughter ended up inheriting it. But they were also brought up in the business. They are continuing to grow and expand into new markets.
The company had some employee management team come in for some training. The consultant said that it was one of the few companies that he has dealt with where the kids didn’t end up destroying the business.
My husband worked for a short time for a company that went down a similar path. He got out before it got really bad.
Grandfather started it. Father grew it. Kids bled it dry and destroyed it.
