This thought came to my mind reading a similar article today:
The poor have little so they should pay more, the rich have more so they should pay less. Though not a new concept, it made me think that people really are more for themselves, than others, at least in the US or we'd be able to nip this in the bud. I mean, there's more poor people than rich. You'd think the poor person would get that the rich person doesn't actually have their best interest.
Which is why we should elect a poor person next time for President.
