The short answer is "no." Capitalism is the search for profits, usually at the cost of everything else. This striving for profits encourages business owners to pay the least possible for labor, and when there is a surplus of labor, the wages can be very low indeed. When the poor are lacking in skills, there is very little incentive to put them to work.
Physician, I am in complete agreement that the economic system is not a solution to poverty; only education is. The question at hand is whether capitalism is good for the poor, and my answer is still "no," for the reasons I gave above. I do not feel that any system is going to be benefiting the poor more than any other. Cultures have gone through golden ages, silver ages, and so on, but for the poor, poverty just is.
