Publicly run stuff doesn't have to be 'shitty', and in fact there are many of us old enough to remember when the city/county power company and other utilities were far and away better and cheaper than the for-profit utilities. The problem is that in order to make people think that government doesn't work and justify privatizing all the public infrastructure the conservatives (mostly Republicans but some Democrats) have spent the last three decades breaking as much of the government as they have been able to.
In three decades of watching privatization efforts all over the world I have yet to see a single one that ended up with better service at a lower price than the previous public system. None. Anywhere. Ever. Can you point at an example of a successful privatization project?
