Students are taught the usual math, english, science, and history. If you want to teach critical thinking and analysis, you're going to need to either displace one of the subject matter or retrain how and what teachers teach.

There isn't enough hours in the day to squeeze in another subject in between high stake exam training and overloading students with homework.

Money doesn't seem to be the constraining factor here. Political reform are needed, and so is the support framework for training teachers to teach in yet "unproven" methodology.
