You're welcome Shadow, and as Becker said, Hong Kong and Singapore are largely service based. The reason why service economies work is because they still invest and derive profit from somewhere, and with that profit, they demand additional services at home.
there are many reasons why Hong Kong and Singapore wealthy.
Many will attribute it to free market. But like I said earlier, they are not libertarian when it comes to crime. and very unlibertarian on immigration.
They're also multicultural, and very small in area. If we stopped here, you have plenty of reason to believe US can never be like them, and we'd almost never want to be.
Taiwan is slightly different, but they all have another thing in common, high employment due to LOW wages and LOW benefits in employment. Many people in the US who are considered "underemployed" would be considered upper middle in Taiwan. In all 3 places, there's very little tolerance for debt, this is not "freedom" by American standards. They do not allow credit cards and mortgages to be blown up, this definitely means lots of potential jobs are lost and prevented, but at a price many Americans would probably kill for.
No system is perfect, and the grass is always greener on somebody else's side. Americans still have lots of benefits people there do not, if nothing else, lots of free space and land to travel. One thing I know about the lifestyle in those countries is, they do not want everything, they live within their means and they frown on people who have kids who they cannot feed. People who have an unwanted child are shunned and shamed, it doesn't happen a 2nd time. They do not condemn abortion, it's their way of saving money.
They are far from Christian as a culture, yet their teens either know how to practice safe sex, or manage to clean up their mess. Look around you, go figure. (sorry for the rant about children, but it's a very real issue when it comes to economics, Americans can be in denial all they want about it).
When Taiwan and Singapore complain about unemployment, its because they have too much talent, and too much free time. Not that they are complaining they'll starve because they don't have money. Restaurants are luxury and most people eat with disposable plastic bags, it's bad for the environment but makes perfect economic sense.
