I just asked basic questions. If the claim is that capitalism does not reward loyalty, does socialism? Is socialism more about morality or economic efficiency?

I actually agree with you. Extremism on either end gets us nowhere. My point isn't that capitalism rewards loyalty -- it's true, it often doesn't! But neither does socialism, at least as I understand it. So pointing to a undesirable thing and saying it's the fault of one system or another is ignorant and silly.
