In regards to what is best for this nation, what do you think would benefit us more in the future?

Everyone needs skin in the game. We need a tax system where everyone pays something, so that when politicians decide to throw money at something shiny and new, all will have a voice. What we have now is "representation without taxation".
Further, with some exceptions, I do not think that many social programs should be just doled out without some effort on the part of the recipient. Requiring able-bodied recipients to do community service such as painting over graffiti, picking up trash, or maintaining city parks builds work ethic and a sense of pride that they are contributing to society until they can get back on their feet.
Implement these, and I think you would see a real improvement.

Be more judicious in starting wars.

Everyone has an opinion...usually based on their own experiences, which are not universal.

That said, I think the biggest impact on improving our future would be to develop a sense of who we are now...as opposed to who were were "then". The USA has had her growing pains, and we're still cutting our teeth-Let's not forget, we're relative youngsters.

Still, we've come a long way in a short time, and our list of good deeds far exceeds our bad.

We need to stop looking for things that divide us, and accept that what unites us are things we generally all agree upon.
