This is premised on the assumption that everyone was trying to "make it" at 22. Outside the little SV social network bubble, founders are generally older with a deep well of experience in a problem domain. I worked at two companies run by their original founders. The founders at both companies were in their late 30's or 40's when they started the companies. They had PhD's, years of experience in the field, numerous papers to their name, and extensive professional networks. They weren't trying to "make it" at 22--they were working in the industry building up a solid foundation for starting a business.
