Moving Forward: Why Looking back should be a resource for good

What seems to be the most important thing in any part of history is remembering. More than anything I've ever seen when it comes to politics is since were humans we really can't remember what happened 20, 30, 40 or 50 years ago or even read a history book. Why does this matter? I live in America where Fox rules, and conservatives use fear tactics to do whatever they want. If you look back into the 90's Bill Clinton's tax rates, corporate and personal were higher allowed government growth and private sector growth. When conservatives say: "Well Regan had a good tax rates, in the 20% so the private sector could make jobs" this statement so all to false. Private Companies want to invest in a progressive society because they now it's sound. They know even if there taxed in the 50-60% they have a safety net. If they fail and have to let off workers they have jobs being created by the government, they know they'll want to invest there because there's a safety net. That's All! When America was in a depression  FDR saved us from trickled down economics and put tax rates up over the 70% mark on the rich. Not because he had something person but he knew if there was one person to trust it would be the people that were elected to serve the USA not people making the most money. He created jobs in all types, art, construction, manufacturing. And that's Progressive Everything.
