I want to believe this but the government has rarely shown that it can run things too efficiently. The employment in those "public" entities, be it education, package delivery and transit tend to become like social programs with benefits we can't afford. Look at the cost of education, K-12 adjusted for inflation per pupil.
Total and current expenditures per pupil in public elementary and secondary schools: Selected years, 1919–20 through 2005–06
Look at this table per student in constant 2007 dollars:
1960: $3,272
1970: $5,161
1980: $6,549
1990: $8,923
2000: $10,360
2006: $11,643
Again: constant dollars per student. Is public K-12 education almost twice as good today as in 1980? Or 3.5 times better than it was in 1960? That's what we're paying for it today.
I have no reason to believe that a "public option" in healthcare would do anything but include highly compensated public employees with a strong union and unaffordable benefits the private sector can only dream about. And I don't see the crowd that wants the "public option" putting limits on trial lawyers or junk lawsuits, either.
This is no anti-government rant. I'd like for a public option to work. But government's track record in running affordable and cost-conscious enterprises is terrible, largely because they are in denial that it's not 1960 any more and the kind of employee benefits we could afford back then are no longer sustainable in today's global economy.
Public sector employment costs simply can not grow faster than the private sector employment costs any more. Businesses and private sector employees simply can't bear that burden any more.
