That's a very interesting perspective.
I'd say that the fundamental, defining difference between conservative thinking vs progressive is that while progressives say "let's change things for the better" conservatives say "don't throw the baby out with the bath water". Conservatives think America is basically pretty good, progressives think it needs it be "fundamentally transformed", as Obama put it. Progressives say "we need to do something" (and proposal X is something, so we need to do it). Conservatives think we shouldn't lose sight of the principles that once made this the greatest country on earth.
If you belief, based on the news you see, that the place is falling apart, then indeed "we need to do something" (liberalism) is a reasonable response. If you believe life is pretty good, and slowly getting better, then you should stick with what's been working (conservatism). So I'd come to the opposite conclusion as you.
If having more women in nursing and more men in programming is a terrible, horrible thing, then we have to do something about it. If black people can never succeed, if it's unimaginable that any black person could ever be a judge, a mayor, or a senator, then we need to do something about that. On the other hand, if black people can be judges, mayors, senators, and even president of the United States, then all the liberal progressivism is unnecessary, and indeed their complaints of being "kept down by the man" are just whining, excuses. If the society isn't basically racist, then Al Sharpton is out of a job. Progressivism REQUIRES big problems. If you don't believe there are big problems everywhere you look, you have no interest in liberals' big "solutions".
Personally, I think some things could be improved. Liberals do a pretty good job at identifying the problems. However, they all-too-often fall into the trap of "we have to do something, and proposal X is something, so we have to do proposal X". Conservatives are hesitant to change things, so they don't screw things up. Perhaps the ideal would be for liberals to set the agenda of which problems we want to solve this year, then for conservatives beancounters to get out their calculators and figure out which proposed solutions have worked well elsewhere or in the past, and which ones are economically feasible. So the liberals force the conservatives to do SOMETHING, and the conservatives ensure that the SOMETHING has a reasonable chance of working, and without making us bankrupt.
