"Liberal" and "conservative" don't mean what they used to. I'm still a conservative, but I'm no longer right-wing, so I think I at least have a basis for comparison.
The entire time I was over on the right, the thing that held me in place was my near-religious faith in the free market. I didn't believe in God, but I figured that believing in business was both not that different and the next best thing. When it was clear that the GOP establishment had lost that faith, the Tea Party formed, and I almost joined them (until I noticed that they were being hijacked by a bunch of social conservatives, whom I have never regarded more charitably than as a necessary evil of big-tent politics).
What eventually pushed me out of the right completely was, first, the realization that free markets don't exist. The market ALWAYS wants government's help to get it to move faster, whether it's slow and needs a push, moving but wants to move more, or overheating and in danger of crashing. Markets don't want to be "free." Trying to "free" them is to build a bridge to the Nineteenth Century.
Businesses do not always operate in the best interests of those around them. Everyone knows this, and the right has always done the best it can to shrug its shoulders at the fact. I wouldn't say that this is a result of "higher" or "lower" level thinking. I used to believe that my superior understanding of economics put me on a higher level of thinking than the leftists I argued with; turns out that I hadn't been paying enough attention to all the assumptions the discipline of economics makes in modeling human behavior, and it falls apart quite frequently.

It's really just a question of what you choose to ignore and when.
