The problem with this is that when the government takes on welfare projects, individuals effectively lose their ability to help these people. This, in turn, makes people more selfish: The people who receive welfare checks don't see the personal sacrifice that is made on their behalf and the people who are taxed do not experience the fulfillment of lending a helping hand.
Another big problem with social welfare programs here in the U.S. is that they often result in able-bodied people refusing to work because they will lose their benefits. It's really terrible to see people become dependent on the government for no good reason, and I've seen this first-hand.
I agree with what you said, but you haven't fully explained how politics work.
