Under ideal circumstances, the invisible hand finds the best solution for people's needs weighted by their wealth. The needs of a poor person do not count at all, which is why we are considering donations. We have many rules already in place to prevent negative side-effects caused by people doing "blindly whatever makes the most money", like enslaving their debtors. The failure of communism does not mean that everyone is better off when we stop thinking about the needs of others.
