Capitalism has lead to an unprecedented generation of wealth throughout the world and has been largely responsible for a significant reduction in poverty throughout the 19th and 20th centuries. Socialism has had the opposite effect.

The wealthy benefit the poor as long as they do not inefficiently utilize resources.

People who support socialism usually do not grasp the idea that the wealthy actually generate the wealth that pulls the poor out of poverty. Any action that a wealthy person engages in benefits the poor.

If a wealthy individual...

Puts money in a mattress: leads to deflation, which reduces the cost of products that the poor purchase.

Invest money: expands businesses, which creates jobs that the poor can take and also generates wealth that can be donated to the poor.

Buy stuff: stimulates demand which leads to the creation of jobs that the poor can take.

Start a business: creates jobs and also creates products that the poor need.

Socialism, on the other hand, destroys the mechanism of wealth generation that pulled society out of the dark ages and inefficiently allocates resources.

When fully informed, the only people who would support socialism are government bureaucrats because they're the only ones who benefit under socialism. Everyone else, especially the poor, suffer.
