Anyone who thinks the first quote is the way that a civilized society lives is a fool. If I work to support other people, why should I work? Why can't I be one of the supported? Eventually, no one works because it is not fair. I work, I pay my bills, you work, you pay yours. See, that's fair.
You look at the quote too literally.
What do you do? What is your ability? That is what you offer to society.
You also have needs. That is what you receive from society.
You purchase what you need from others and other purchase from you what you offer. There is nothing explicitly stated in the quote that says "without purchase or reimbursement".
