Why are so many people just plain stupid?

In my world no one would dream of taking on an interest only house loan that they could barely keep up with knowing interest could go up or that they would need to pay principle some day? And why would banks loan money to people with no hope of repayment? And most important; Why is our federal government acting like a parent that wants to be liked by bailing everyone out. How in the world can this country ever be great again when everyone acts like morons? How did we ever go from most people doing the right thing and caring about their fellow man to a society of selfish little babies? Sorry for the rant but what I really want to know is how many of you really give a crap about working to make America a place to be proud of again instead of just getting what ever you can take from her? I am asking rich as well as poor here.
