I think these discussions are immensely helpful. Mostly because they give us clear criteria for accepting and rejecting proposed solutions. Many people, for example, are for confiscatory taxes on the rich to level the playing field.
Your sentence here, for example, implies that the wealth concentrated in the hands of the tiny percantage of the population would relieve the millions who struggle if it were just redistributed. I don't believe the numbers back that up. As rich as Gates and Bezos are, they can't fund healthcare for everyone. Which is why redistributive tax schemes aren't about using the means of some to fund the needs of others as much as creating fairness (or at least the sense of one).
