"Sweden’s impressive start-up record can also be attributed to some broader aspects of how the country is set up. Its social safety net, for instance, helps entrepreneurs feel safe to take risks. In Sweden, university is free, and students can get loans for living expenses, which allows anyone to pursue higher education. Health care is free too, and childcare is heavily subsidized. None of these benefits are contingent on having a job, which means people know that they can take entrepreneurial risks and still know many of their necessities will be covered.
“I think if you want to be an innovative country, you have to give people security so they dare to take risks,” Mikael Damberg, Sweden’s minister for enterprise and innovation, told me."
The second case, which is not present in the article is that in Sweden, working in a small company is considered a risky proposition and a such small companies are offering higher salary than big companies. It means that they tend to attract the best people too. In most of the rest of Europe (DK, DE, FR from my own experience), if you want the engineer path with good money, you need to get hired by a big company.
