I figured this is what you meant with your earlier statement, and I can fully understand it.
Attacking & eschewing the system might be the very definition of 'radical'. When one doesn't believe the system is working for them, they tend to go outside it. It's a natural progression.
Now the question, is:
"Given globalization, is our system itself adding unneeded oppression? Or, is it doing its best to deal with a changing world?"
I'm going to claim our current system is suffering from both effects, and that's not to absolve the aspects of the system that are advantageous & oppressive.
As global effects continue to erode the American standard of living while fully participating in a capitalistic free-market environment, its only natural to consider the possibility of other systems. i believe this is the reason many, particularly young people, are willing to consider Socialism, or perhaps what they believe is "Socialism"?
As for me, I'm an avowed capitalist. Capitalism has brought more out of poverty than any system yet tried. However I must add a strong caveat, here:
"For Capitalism to work for the betterment of society, it must be tempered with Social Restraint!"
It's with this last, 'social restraint', that I believe we Americans fall a bit short.
Of course my last statements exist within a framework where one believes our economic system should be beholden to the betterment society. Some others believe the converse. But that's a whole 'nother ball of wax!
