Ok, I don't think $150k will actually make you less poor, nor make you work any less. What it does allow is a little more leeway, say if you have bills that need to be paid. Maybe you are not right out of college so car payments, house payments, etc... might need to be paid while you take 3 to 6 months off form work. I like that it shakes things up in the VC & Angel world because they need to be shaken up. You are dealing with statups, you can't be risk averse... go invest in mutual funds if you don't want risk.
Congrats YC and Yuri, wise investments. Oh, this is not a bubble this is the same pattern that came about in the 1930's and 1940's with Great Depression and the auto industry. It's simply happening again with the internet industry (steam engine == bubble/economically unfeasible long term && combustion engine == years of growth/redistribution of power and wealth; dial-up == bubble/economically unfeasible long term && mobile/high speed == years of growth/redistribution of power and wealth)
