Our standards of living have increased, and that's nice. But there is no question of whether or not anyone deserves to live. You simply live, until you don't, like all life.

The increase in standards of living isn't because we have eradicated the underlying animal needs, but rather, because we have been meeting them effectively. Sadly, this is only in the short term - we have major species-wide issues with our long-term course, but that, perhaps, is another conversation.

In any case, by denying the fundamental system you are based in, and demanding that survival not take any energy, you undercut your own foundation, and that causes problems for you.

Human rights are a social contract. They are nice, and we should keep them. However, they don't eradicate the animal and natural foundation upon which we stand, and they absolutely must bend to necessity.

You have an animal right to exist until you die by natural processes, like disease, old age, predation, etc. You have a human right not to be tortured, enslaved, etc, because that is a goal we all agree on. But you don't have a right to have other animals take care of all of your needs when they don't want to. That would be slavery.
