On Skid Row: Why hasn't anyone done anything!!

When I saw this video their was a question that automatically popped into my head. WHY? Why isn't anyone helping these people that are just like us with the exception that they aren't as ignorant of these situations as we are. I bet that if we switched places with them they would help us out until every single homeless person on skid row had somewhere to call home and roof over their head. So why can't we do the same? Is it so hard to donate a few dollars that we will probably spend on something unimportant to them? Los Angeles should provide more housing for these people because they are responsible for the homelessness of all those people. If they really cared about them they would do everything they could to keep them off the streets.
It's amazing to see that even though these people have lost everything they still have hope and still count on God to help them out when all else fails. They haven't lost faith in God and they struggling everyday to survive because they want a better tomorrow.
If you think that we can't do anything about it and that it doesn't affect us you are completely wrong because there is something that we can do and it affects us more than you think. We can donate money, clothing, food, and tents just as we did when Haiti needed our help. Just one person can make a huge difference because if that weren't true those 33 miners in Chile would still be in the ground. If we helped Haiti out why can't we help those people on skid row that need all the help they can get. This all affects us because our ignorance is pushing these people to become the criminals that might come right through our doorway one day and that may end up locked up afterwards. Instead of creating criminals out of those people who get so desperate that eventually have no choice but to become one, we should help bring out the good in all of these people and help get them off the streets and under a roof.
Imagine if it were one of you; wouldn't you want someone to be humanistic enough to lend you a hand or atleast buy you a sandwich when you were starving? I think you would so why don't we all get into their shoes and do what you would like others to do to help you out if you were in that situation.
