These venture-funded startups make a mockery of the concept. After all, if you're a true entrepreneur, are you
really going to waste 6 months of your life asking a fucking venture capitalist for permission to be a founder? The VC-funded game is just the same private-sector social climbing that a previous generation called "the corporate ladder".
The real problem, the 9500-pound chain-smoking and belching elephant in the room, is that almost no one can bootstrap because the U.S. middle class is nearly gone and almost no one has any fucking money. In the 1960s, with strong unions and low housing costs and cheap health insurance that covered everything, worker bees actually could save up and have starting capital. The Satanic Trinity (housing, healthcare, and tuition) that is now killing the middle class wasn't even on the horizon, so people of average means had a real shot at starting their own ventures-- without having to get permission from a bunch of effete Sand Hill Road bureaucrats.
Add to this the obscene cost of living in Silicon Valley. Even the people with supposedly well-paid corporate jobs can't afford to buy houses. The only real way to make money in the Valley: be a landlord. Whenever entrepreneurship revives on the North American continent, it will be far from the tapped-out, overpriced, landlord's paradise wasteland of California.
Ok, so on to the finding itself... I agree. Most people who launch successful businesses had to learn on someone else's dime and risk before they had the capital, skills, and domain knowledge necessary to go on their own. It's pretty rare that a 22-year-old, fresh out of college, has (a) the leadership skill to create a business from scratch, and (b) insight into a real-world problem that can actually be made into a business. These VC darlings aren't true entrepreneurs and shouldn't be taken as typical; instead, they're rich kids whose parents are laundering family connections so it looks like their underachieving spawn are "startup wunderkinds" instead of well-placed halfwits that Wall Street didn't want.
