The conservatives can slow, but not stop the progressive liberalization of America. Conservatives want to return America to 1950, but they are losing every liberal/conservative battle. Name one aspect of America that is more conservative than it was in 1950.
There are 100's of aspects that are more liberal today: Church Policies, Gay Rights, Black Rights, TV Programming, Medicare, Medicaid, ObamaCare, and on the list goes, all for the betterment of America.
They are the road bump slowing down the drive to a totalitarian state that Democrats lust over. The state over the individual is the goal of the Democratic party, because Democrats are too cowardly to handle life's problems on their own. So they want government to do all their thinking for them. Of course, I can understand that, as Democrats don't know how to think, reason, discuss, or present rational debate. You are the perfect example of this, like foxnewschecker.
Many Liberals love Progressivism and the direction it's taking America! Soon they'll be able to have sex orgies in public with anyone that wants to have it, including children. Liberal judges in Blue States already give child molesters very lenient sentences. Now that's what Liberals call real progress in America!
Setting aside politics and the obvious negative issues of the period, from personal experience, I think the best timeframe was 1955 - 1965 ... peaceful, prosperous years of progress and fun (the greatest cars, the best Yankees players, color TV, 707, Beatles, REAL freedom, etc.) ... the systemic shock that started everything to unravel was the assassination of JFK, then the war got way out of control after 1965 ... and, well, you know the rest ...
Tax policy is far more conservative than it was then. Rules protecting rich people from poor people are also more conservative. Socially we are more liberal but financially...which is what conservatives really care about...they are winning big.
