A free market economy helps everybody all the way around. Some people foolishly say capitalism means that the rich get richer and the poor get poorer. This is demonstrably false. In a true free market economy, that the rich get richer and the poor get richer. The poor in America today would be considered middle class in most countries around the world.
Poverty is a relative term.
This did not happen by chance. It happened because a free market economy always tends, if left unmolested, to up the economic ante. It tends to produce better goods and services at a more affordable cost. This means that people can buy more products or services for less money, and have more money left over. The free market economy allows men to contract with employers, just as they contract with one another in any economic transaction.
