USA has 33 times the population of Sweden so if it was solely a product of a political system I would expect at least one other "Silicon Valley".
Considering that the distance between the East Coast and the West Coast is the same as the distance between Sweden and Egypt, I assume a second "Silicon Valley" would be viable.
But that was not my point. My point was how low the barrier for "great benefits" where even for "spoiled" software engineers in Silicon Valley. Why not try to move the goal post a bit further?
Maybe something like the government covering 70% of the your away pay (capped, obviously), and giving the company 15% to go toward to whatever they chose (covering you more, hiring a temp, the bottom line, etc.) The size of the company could also be a factor on how large that payment is (the smaller the company, the larger the percentage).
