I think you give Carter way too much credit...
He really was a weak, vacillating president who let everyone push us around.
He was completely ineffective with his own party controlling both houses of Congress for his entire term.
The only area where Carter deserves credit is his energy policy, and even that is no "home run". But I agree that he was too weak-kneed. Nixon and Eisenhower were far better presidents, both of whom supported more vigorous infrastructure investments, the New Deal approach to protecting labor from capital flight, and the sensible regulation of the economy.
But I think, oddly, presidents like Carter and Obama benefit the Right far more than the Left. Why?
Because they are easier for the Right to push around. The Right does not want an FDR or LBJ because these men were ruthless and worthy adversaries. [They don't want the Clintons either, who are far better at hardball than Carter or Obama] FDR and LBJ didn't apologize for their policies, or ape the language of their opponents, or appease the obstructionists on the other side. They had a "**** you" amoral approach like Cheney. Love 'em or hate 'em, they served their party like warriors.
Eisenhower taxed the first 250K at over 90%. He was a hero because he paid for the Interstate system, which had an incredible multiplier effect for business. He didn't put it on a credit card like Reagan, who signaled the permanent transition to deficit spending. He didn't borrow from China so he could give the wealthy more and more tax cuts; he paid for the shit we needed and he didn't listen to voices in his party who said government couldn't do big things. He was one of the best presidents in history. And he warned us about what would happen if we let military special interests dominate foreign policy. If he was on the ticket in November, I would vote for him without a second thought.
Carter and Obama were only allowed to get near power because they didn't have the courage or political skill to overturn the status quo. Their purpose was to help John Galt get higher returns by freeing capital to seek cheap labor in freedom-hating nations. This is why both of them packed their economic teams with neoliberal free marketeers who would protect John Galt from the democratic redress of those whose jobs he was outsourcing.
Both Carter and Obama are like the basketball team, the Washington Generals. Remember them? They were the faux opponent of the Harlem Globetrotters. They were paid to lose, and look stupid doing it. The Left hasn't had support for their policies since Eisenhower, Kennedy, LBJ and Nixon - the four great centrists who got both parties to pass policies designed to help the middle class. Everything after that can be considered as the slow rise of Reaganomics and neoliberalism. Everything after the four great centrists can be seen as the corporate take over of Washington and the death of the middle class consumer, who was handed a credit card and subprime mortgage to make up for the jobs that were outsourced and the money which wasn't trickling down.
