They are also generally centralized federal systems ran by the national government not a decentralized system that hands out vouchers.
So you basically have somehow looked at that list and decided that in order to compete with countries that out perform us we need to do the complete opposite of what their doing.
I do take issue with some of the results (as mentioned in the article). For one China is a horrible country to even have on that list. It's by no means insight into how the nation performs as a whole. The US scores are an average. There's no doubt that better US schools in wealthier neighborhoods (yes poverty is also a problem in the US and not a large problem in Finland/Japan etc) the US is very competitive.
