with regards to becoming an entrepreneur for simple need, I've seen this happen a lot in my country (specially in my region, which is quite poor): a lot of people doing business simply because there aren't really any other options. Same happens in the countryside (many people don't see agricultural activity as 'entrepreneurship' though).

Also, the number of startups tends to rise during recessions could be interpreted the same way: the more people lose their regular jobs, the more entrepeneurs enter the rig. Talented or not, willingly or not... [1]
