> there’s a disturbing trend developing of people deciding to found a company simply to get rich

I understand what the author is getting at. But the purpose of a business is to make money. What's wrong with starting a company to get rich? My suspicion is that the author means something more along the lines of "There are too many people starting companies simply to make a quick buck."

All things considered though, I agree. There are simply too many people in the Valley chasing huge valuations and quick exits and not enough building sustainable companies.
