Sure, agreed though a larger percentage of VC funded startups exit than you probably think. Those "90% fail" stats are made up mostly by people who got traditional angel investment or no investment at all.
I'm just saying there's two sides to the coin, that's all.
I think there's a very genuine element of 'show me how motivated you are' you also cannot expect to get a normal standard rate company salary when you own most of the equity and aren't profitable. I think it's reasonable on balance.
