Strange that you see pain, turmoil, sorrow, and such things, as being bad things. They are the things one uses to understand problems and give meaning to joy and life. I mean look at wealth as an example: The richest people in the world can afford literally anything they want. Any item, as many pretty trophy waifus and prostitutes as they desire. They could buy friendships, even, and never worry about running out of money for them. They could save anything they care for, or at least give it the best possible fighting chance with an army of doctors and lawyers and so on... And yet some of them still manage to be depressed. Unhappy. And so on.

Joy means nothing without pain. Victory means nothing without obstacles. We are mortal creatures that live to do that which we wish to, but without obstacles, struggle, pain, setbacks... Life has no meaning.

As well, your personal bias is showing when you state that their lives are worse. According to who, you? Me? The skydaddy? It is their life. Let them choose to do with it as they please so long as it does not infringe on someone else's life. If they wanna drink until their liver bursts, let them. If they wanna become professional boxers and risk brain damage later on in life, let them. If they want to play every video game ever and be fat fucks, let them. I can still laugh at that, or scratch my head in confusion, but then, I am not any I'd those people. The fat guy might actually like being fat. The boxer might actually enjoy the thrill of being injured.

You and I are not gods. We do not get to arbitrarily decide what is the "best life", consensus gets to judge that, and it is up to you, me, and whoever else, to try and argue our case if we feel it is important enough.

And -that- is democracy in action. Human rights come into play to prevent tyranny of the majority.
