that reads like a rationalization of selfishness. however, the rationalism underlying capitalism neither attempts to encourage nor discourage amoral behavior.

capitalism instead acknowledges that people will sometimes (often?) have selfish intentions and redirects that penchant toward productive economic purposes through competitive counterbalance.

it's still not ok to be a jerk, but if you are one, the system counteracts your selfishness with that of others to reach a greater good (in the form of efficient allocation of resources). "because capitalism" doesn't excuse bad behavior; rather, it brings bad behavior out in the open so other social structures/norms can deal with it.

Unlike socialism where people do what exactly?
