I disagree, Clinton and Obama both were free trade,even criticized for it. I think the vast majority of economists on any side, all sides, agree that it's easily the best course, and most of our past presidents were try-hards that listened to experts.
I think dems are more pro-labor and pro-health insurance and pro-higher taxes on the ultra-wealthy. In other words, let the economy grow and free trade flourish, don't let government intervene there. And based on the biggest winners, shave some of those earnings off and pay the employees that made that possible back, via higher wages, health care, relatively low taxes, and infrastructure, etc.
Imagine a giant "mine' full of precious metals. If government tries to control mining, it will be **** we all agree. If we let private compete and do it, it will be FAR more efficient (in most cases), but if they have no rules at all, monopolistic issues and abuse of workers always occur. Instead, let private do it, but restrict them in ways that force them to do it safely, and to compensate workers fairly.
I see Republicans tend to alwayspush for the corporate interests at the cost of everyone else, and Dems push for the "everyone else" at the cost of the absolute richest and most powerful people...who will arguable not suffer at all if they have to pay a little more from their overflowing coffers.
that got partisan, but it's what I see anyway.
I think liberals/progressives change as information and the times change...its part of what it is to be liberal/progressive. free trade is always the winning strategy, it's just what you do with all the profits from that free trade that we allow. Do you let only the top 0.05% gain the most, or do we ensure that they help share that with the workers that made it possible, but who lack a union or capital to bargain with.
