In a capitalist world, it can be hard to remember this. But despite what you are pressured to think, your value as a person does not come through what material value you create for others.
What does an infant contribute? How about a paralyzed person? How about a developmentally disabled individual? What is the value of an elderly, dementia-stricken grandparent?
So what is your solution for the paralyzed, the crippled, and the terminally ill? Are they a drain on the system, better off put down like animals?
