You are correct that I don't know anything about Singapore other than what I read in the press like the Economist and the CIA Factbook.
However I do know quite a bit about analyzing high tech enterprises, and the creation of said enterprises. And that analysis is a bit more nuanced than 'health care is more expensive.'
The Singapore Statistics Office disagrees with some of your numbers [1] they claim 4% unemployment. But it doesn't say what they spend on health care.
But lets say your ideal employee in Singapore cost your $70,000 USD / year. In California you can get health care on an individual basis for $500/month for most people, $1000 a month for older people (60+), and a lot less for young healthy people. But lets say you spend $1000 a month. So that means a $12,000 per employee per year health cost penalty. Now 25 employees at 70K each is a salary pool of $1,750,000. If you hire Californians at $70,000 and give them each $12,000 for health care ($82,000 effective salary) then you can only hire $1,750,000/$82,000 or 21 of them (and $28,000 left over in your pool)
So here is a different, but an important question. Can you achieve with 21 engineers in California what you can achieve with 25 engineers in Singapore? (this happens to be an interesting number because for those of us who have lived in the Bay Area for a few decades there is a saying that goes "With 20 people and a good idea I can change the world!")
I'm not trying to take anything away from Singapore, I'm sure its a great place and everything I read says it has great infrastructure and a very business friendly climate. What I'm saying is that using health care costs in this way is not an effective reasoning tool with regards to a high tech endeavor. Twenty technical employees who have already done a start-up or two each are going to be hugely more productive getting a new endeavor off the ground.
