When Donald Trump campaigned for president, he told the American people that he would be a different type of Republican, that he would take on the political and economic establishment, that he would stand up for working people, that he understood the pain that families all across this country were experiencing. Well, sadly, it was just cheap and dishonest campaign rhetoric that was meant to get votes, nothing more than that.

In fact, for just about 1/6 of the cost of an Iraq War, we could have put the social security system on sound financial footings for the next 50 to 75 years. The problems can be managed - but not if we continue to fight this war for another 80 years.

And you don't do that by giving a tax cut to the big winners and raising taxes on those who have not done very well. Your economic policy has to respond to the way our economic system has been working.

Unfettered market American-style capitalism doesn't work. Developing countries can't afford that kind of luxury. They just can't afford it. Period. If there's a mistake, they can't afford to put out $2 trillion.

The battle for the past will determine the battle for the present. So it's crucial to get the history straight.
