As far as taking care of our poor, our sick, and our elderly....
It's not like we are not trying.... or at least throwing money that way.
US 2009 Federal, State, and Local Gov't Spending:
$764,400,000,000 in Healthcare
$406,900,000,000 in Welfare (includes unemployment)
$738,600,000,000 in Gov't Pensions
Now to put this in perspective: Again the same 2009 #s
$90,000,000,000 in Education
$84,300,000,000 in Transportation
$186,900,000,000 in interest from the deficit
