The fact is that Liberalism has failed wherever it has taken hold and there is no denying that fact. Michigan is one example, certainly, but there are many others.
Thomas Sowell summed it all up very nicely.
"The world of reality has its problems, so it is understandable that some people want to escape to a different world, where you can talk lofty talk and forget about ugly realities like costs and repercussions. The world of reality is not nearly as lovely as the world of Liberal Land. No wonder so many people want to go there".
Unfortunately we are all ultimately stuck in Realityland and the sooner we all acknowledge that, if we are intellectually capable, the better.
