The whole "do you like the DMV and Post Office" argument is BS if the goal is to argue against Single Payer/Public Option systems (having neither is why we spend about double what other industrialized countries do and we get mediocre outcomes in some key areas). I could just as easily turn it around and ask 'do you like the customer service you get from (fill in the blank private business)?' How did you like that (private) customer care rep? Was he/she clear, concise, courteous and helpful? Now that you're warmed up, answer these questions:

-How much do the people in Chicago enjoy having the cost to park at a meter quadruple since the parking meters were privatized a few months ago? Note that the spots are no bigger and the streets are no nicer.

-Have you ever received cold food or the wrong order from a (private) restaurant, even after you waited (for 30 minutes, 60 minutes or more?) to be seated?

-Have you ever waited in a long grocery store line with just a few items while people ahead of you with full carts haggled over pennies and coupons? Did they squash the bread under canned goods when you checked out? Did they scan the same item twice?

I am not by any means suggesting that I want public restaurants or grocery stores, etc.. But when it comes to The Commons that we all depend on, yes, I want the government in and the profit-motive out for health insurance, because again the facts show that means lower costs with good service (note that the Business Roundtable Report On Healthcare "represents CEOs of major companies"). And of course the real answer to the above questions, parking costs excluded, is "sometimes".

PS---Honestly, the vast majority of the time my mail gets where it needs to be on time and at a very low cost. And I've had courteous people and short lines at the DMV in addition to the opposite...just like with any private business.
