Why just the last 40 years ? Equal rights ? the timing is about right.
Civil rights among others. There was a time when the democratic party (discounting the dixie-crats, who were functionally their own party....) was, genuinely, about equality, about liberty.
That is no longer true. The civil rights movement has been taken over by the keep-them-voting-democratic movement. Give us just enough to make us dependent, and then build the fear that we'll lose what we've gained if the democrats aren't their to keep us in their clever little traps.
But they don't truly care any more about advancing the causes of liberty. They take on high profile causes such as the gay rights movement to make a showing of being on the side of liberty while painting republicans to be on the side of totalitarianism. But when one looks closely, there are far more examples of liberal democrats pushing for more government control, more intrusive government programs and more invasive government policies than they can possibly counter with a list of policies on the side of liberty.
Of note (one of many) is the fact that even with a democratic majority in both houses, the FISA bill was modified to include more government authority in defiance of constitutional protections - just as Bushco wanted. Why is that, unlesss the democratic party is not TRULY against FISA and the like, except that it was a republican idea. Sorry, but democrats can no longer (at least to a thinking person) blame the republicans for pushing it through against their best efforts. Even Obama voted for it after promising to fight it all the way. I'll bet he is inwardly grinning like the cat that ate the canary, anticipating how HE is going to use that authority.
Doesn't that make you wonder about his other promises, such as keeping his tax increases to income levels above 250K? What excuses will he find to claim taxing us all at greater rates - except the extreme lower income levels who already pay no taxes?
And of course, the democrats are literally drooling in anticipation of pushing through economic regulations by the bucket full after successfully lying to the public about lack of regulation being the cause of the melt down while denying that CRA and other federal mandated regulations played a part. How they seem to forget that one: heavy economic regulations during an economic slump have always, in the past, made the slump worse; and two, many of the "open capitalism" laws and free trade treaties now being railed against by democrats as "proof open capitalism does not work" were instigated under - and promoted by - democratic administrations.
But facts do not matter. All that matters is the democratic party is going to get their chance to add any damned regulation they want. Have fun, assholes. Because when it keeps going down the drain ever faster ala 1931/1977, we unfortunately don't have anyone in the wings to pull us back like we had the last times. But then we will finally have what dems have always wanted: every one will be on the same economic level under a bloated, do-exactly-as-we-say-and-we'll-take-care-of-you totalitarian government. That we'll all be third-world poor (except the PTBs in government) and without any means left of defending ourselves against unreasonable search, seizure and arrest is beside the point.
