We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Nobody really believed that Obamacare would do anything to improve our health-care system or, even more absurdly, "bend the cost curve." By vastly increasing the number of insured and therefore of demand for medical care, it could only drive up costs. Remarks like Nancy Pelosi’s about having to pass the bill in order to see what’s in it showed that they weren’t really interested in what was in it — and nor was the President, who left all that up to congressional Democrats. What they cared about was the establishment of the progressive principle that the government should be in charge of overseeing health care. The details would be worked out later as history pursued its inevitable course of increasing government control over people’s lives.
Leftists take the long view, the Gramscian approach. At one bite at a time, their growing Leviathan wants to consume all that it can of private life in America. It's never enough, and never will be.
That's the essential problem: there is no end-point.
Less because progressives are linear-thinkers and more because linear-thinkers are naturally progressive (every new generation must be smarter than than the previous, because it has had more time to learn, and has access to a larger volume of past-generated experience --this is how 'children lead the way').
Ergo, when their ideas go wrong, it can only be because some faction of unenlightened 'bad' people have (deliberately-or-not-it-doesn't-matter) subverted progress.
If you are a progressive unhappy with your life, you may take this very personally, and may be an easy follower (or look-the-other-way-er) of some sort of 'cleansing' of the species.
Which you may see as 'needing doing' and lacking only a 'strong leader' to get it moving.
The caution for the rest of us is to always remember the characteristics of linear thinking. The charm of a rustic digging fencepost holes only at the full moon, in order that the posts may stay straight, is a char found along the road to Auschwitz, or Hell, pick one.
