Ask HN: High Salaries and Lots of Jobs = Great Enterpreneurial Environment?

I remember reading an economic survey of Sweden where they credited the large number of successful Swedish startups in the 70s and 80s to a lot of Engineers and a lot of jobs around in case the startup didn't work.

This sounds a lot like Silicon valley - what do you think?

(p.s. I can't find the article about Sweden anymore)
