They also look down on people who could not take the risk, calling them cowardly, lacking boldness, entrepreneurial spirit, etc.
"Sell everything and fund my startup" is fine when you've got a 12 month emergency fund, living in a paid-off home, , and you parents are able to bail you out. It's not fine when failure means you're penniless and homeless.
Further: it's much less of a risk when you have a metaphorical rolodex of wealthy friends from university or business school. You're not cold pitching - not even slightly. Doors open for you, instead of being slammed in your face.
Yet they'll tell you shit like "Try hard enough and you will succeed! I worked long and hard, people saw that, and were willing to invest. Good hard honest work is rewarded."
The people working on their startup 12 hours a day who don't have connections have no idea that the bit left out is that "people were willing to invest in my idea because we chugged beers together in the basement of Sigma Chi."
