Alright
@magicjuan?
I'm not sure there's an inherent bias toward capitalism mate, there's loads of anti-capitalist sentiment around atm. People are still skeptic of the alternatives though, and do you blame them really given some of the experiments that took place during the 20th century? I reckon it's tough to make the case for alternative politico-economic systems because we struggle to find examples of ones that actually work or provide the basis for human progress in the way that capitalism has/does. Is it perfect? Of course not. But then it doesn't claim that it is (unlike some other systems).
I suspect you'll know this already, but even Marx and Engles praised capitalism because it helped increase productivity and build industry, created open markets and therefore improved trade and freed the 'serfs' from their feudal bonds and all that. Ok, they saw it as something that could lead to socialism, but even they understood its benefits, so there's my answer to your question without even bringing up capitalisms ability to provide humanity with more innovations, choice or freedoms.
See, there's nothing that suggests centrally planned altruism is a given either, is there? Some of most eye-watering acts of human cruelty have occurred in centrally planned, non-capitalist states.
With all this said, though, that doesn't mean there aren't substantial issues with the current system. Like you, I'm concerned with an ever growing disenfranchised majority and huge gulfs between rich and poor. I suppose I'm just not interested in throwing the baby out with the bathwater and reverting back to systems that evidently don't work, if you get me?
