I'd like to have seen more on the socio-economic background of entrepreneurs - does YC collate this diversity data? The stuff about the Chinese famine is interesting but I don't think can be generalised beyond China. My sense is that there are two socio-economic backgrounds that become entrepreneurs - those who are (not to put too fine a point on it) "poor" and so have no assets to risk in starting a company, and those that are "rich" that are also not risking much because their family or others could support them if the company failed.
