Being poor is not a sacrifice. Being poor is a condition in the terms of your life. A sacrifice is being frugal, being diligent, and working hard at self-improvement - Do all poor people do that consistently, as a quality of being poor?

Of course not; being poor is a condition, it is not a sacrifice. It holds no merit as a condition. You cannot use your lack of capital as a bargaining chip at the table. It is not a sign of your deserving more money. If you work hard and do something good for me, that I am willing to pay for, then you deserve money.

Capitalism is altruistic. It functions when people do good, valuable things for each other and establish trust that payment will be provided for that value. It has nothing to do with your status as poor.
