At the government level, it’s mostly driven by ideology. I never came across a situation where a service improved after being "liberalized". Never. Not once. It is always end up in a combo of: poorer quality and (much) higher cost.

I’ve seen too many cases where people suffer the consequences of their own ideas being implemented (large or lower scale), convinced that if we just turn this knob a little more, it’ll finally work. Because of that, I don’t spend much energy on them anymore.
