See I would argue trick question: Everyone having the right to have food and shelter, no matter how smart or dumb they are.
You're right, we absolutely can adapt. There are plenty of historical examples, like say Germany after WWI, when they got completely crippled financially. They did a FANTASTIC job at adapting and everything worked out.
You are confusing right with entitlement. Having a right to food and shelter is not the same as being guaranteed food and shelter. Do you have a "right" to food and shelter in America? Go try to raise a family in the woods in a log cabin in some parts of America and see how many rights you have.
And then you go straight to fucking Hitler. I don't even know why.
