Capitalism is the only system that allows for both of these. We should not stop advocating capitalism, nor should we stop caring about ourselves and others in peaceful, voluntary ways.
I find it no less disturbing when someone says both capitalism and socialism are extreme and they seek a middle ground than if someone were to say both love and cruelty were extreme, and they therefore seek a middle ground. Some vices or virtues are found in moderation; some are found in absoluteness. As Barry Goldwater famously said,
Extremism in the defense of liberty is no vice! — Moderation in the pursuit of justice is no virtue.
Capitalism is just. Socialism is unjust. There is no “messy middle.”
