Our country is a bit larger than yours. Anything socialized would be expensive as not everybody would put into it. Yes, the lawsuits go away as you can't sue the government, but that's logic I save for a different discussion - tort reform. Anyway, the money's gotta come from somewhere, and there are other more pressing issues that take priority for me.
I wouldnt think size matters when it comes to this paricular topic, methodolgy, I think would be key.
