comment: OP, what can people do about it?
  Vote? They are one voice in an ocean of 300 million. Their voice accounts for .00000000333% of America.
  Help the homeless? Most people are trying not to be homeless themselves and at most can only spare a few dollars. Something that will at most buy one meal at McDonalds.
  The people who can actually do something are the politicians in office, and the way you tell them if something needs fixing is to complain.
