If you went completely hungry yesterday, nearly starved to death, but today you get enough calories that you feel less pain so you can at least stand up and walk around a bit, while you watch your brother stuff his face with so much cake he has to puke 3 times to make room for more, to then play frisbee with the rest, what would you think? How it was for you yesterday isn't the standard. How it is for others, today, is the standard. It's about fairness and human dignity, nothing more and nothing less. If everybody was starving, we wouldn't even have a name for it, or a problem with it. It wouldn't be a slight on anyone.
Some people shriek in anguish or sob in darkness, kill themselves, over issues that would be a 2 minute phone call and a check that is 0.0001% of their monthly income for someone else. That's a problem, and that kings used to have less than the average homeless do today doesn't change that, and isn't something capitalism gets to take credit for either. Humans have been inventing and improving things since before history, even animals do it, that's just normal.
