Earlier quoted context omitted.
Economic freedom is very underrated compared freedom of political expression. There are many ways in which Singaporeans are much more free than we are.
Economic freedom (which I'm presuming means "lower taxes"?) isn't much use to you if you're executed for possessing drugs, or indefinitely detained without charge, need a permit to assemble, can't criticize the government, etc.
Erm, all those things(+) can, and do, happen in 'free' countries. They're just not officially sanctioned and are reported differently. If you were to look at this objectively (without depending on just the official figures) I'd say per capita, human rights abuse / exploitation is worse in the US than Singapore.
(+) and worse, eg: get executed for being the wrong color at the wrong time and place
