1) I don't get your first one... Lifetime employment is generally seen to be a bad thing for the average worker. Workers it is said should always be looking to jump from job to job.
2) If you did ban everything but solar... it probably would work out... eventually. I imagine that solar solutions would come around quite rapidly. They just wouldn't be the most efficient or best economically. Markets are actually quite good at making what's demanded appear rapidly.
3) Healthcare costs probably can't be solved by the free market for one main reason. Healthcare is the one area that most people won't ever want a "second class" option for. You need state funded healthcare to force second care options and force people to wait to treat certain things, test for certain things because on the margins people don't often benefit from it. In general it's a matter of cost vs choice.
