All you need to understand about the working class is as follows:-
1) Give them money, they will spend it
2) Offer them a 'cheap' mortgage, or any form of credit, they will take it
3) Give them a flag, they will salute it
4) Give them a national anthem, they will sing it
5) Give them an ideology, they will buy into it
6) Give them an army, they will join it
7) Give them a tax rise, they will pay it
8) Give them a problem, they will solve it, give them a mountain they will climb it, give them a deficit they will pay it.
It;s the people who already have enough that insist on more, the greedy people. They don't want to pay any debts off, they just want more for themselves and will go to great lengths to keep what stuff they have and get even more of that stuff, it's not a matter of need, just a matter of greed.
That's why you have a govt. to stop the greedy powerful people and corporations taking everything and making sure they pay their fair share in taxes, they doesn't seem to be working at the moment. Channel money from the powerful and greedy to the working class and your economy will grow again, it's not rocket science.
In the mean time stop making war with the world, the Arab Spring is happening because of the internet, not US foreign policy. Social networks will bring about changes that the political interference and US taxpayer dollars have failed to do since the end of the last war.
Don't make war with the Taliban, give them access to the internet and an X-box, how long before they are playing Fifa 13/Black Ops 2 and dancing gangnam style.
Who knows, I bet some of those Taliban commanders would be pretty wily Diplomacy players, introduce Webdip to the Middle East and help prevent World War III.
