There are no strains of Capitalism. There are only different people with different morals and ethics (and some complete lack of all) lack of empathy and so on, which is what creates (what already created) what you see as "different strain" of what you are sold to as Capitalism.
What all of you still don't get is that there are no different versions of Capitalism, there is only system, what is different is how people understand this system, what it does, how it works, etc, and what people want to do about it, how they want to regulate laws to control it, which is where political ideology of Socialism comes into play, and so on, which is what shapes different OUTCOMES in different nations, which use Capitalist economic system, because they have different level of population education, awareness, morals and ethics, and culture, which shapes political ideology of the nation.. and whether of not Capitalism will be kept in control or not, and of, how much, etc.
