What Grade Would You Give The Government Over Decades Of Managing Various Programs?

It is a myth that the United States government fixes a problem when it is a crisis. The government has a terrible record on "fixes" unless the solution calls for a military fix; like Pearl Harbor and 9/11. Even then, since WW2 Presidents and Congress have more often than not undermined the fixes.
When it comes to non-military crises, the government has an almost perfect record of FAILURE:
Fannie Mae and Freddie Mac to fix the mortgage loan problem and brought about the banking crisis last year,
the Department of Energy which cost a couple of hundred billion since it was formed to fix the imported petroleum crisis and the percent imports has increased since it was formed,
the War on Drugs which cost hundreds of billions and only filled our prisons to overload but not prevented a multibillion dollars per year illegal drug business from thriving,
Medicare which now costs over ten times per year what it was projected to cost (this is the model for ObamaCare cost), Medicaid same failure as Medicare,
American Indian Reservations which keeps those people in poverty with a bad government -run health system,
the Social Security system which has increased FICA taxes on employers and employees from an initial 1% each to 8% each today and is broke (it's too late for those in retirement or close to retirement but for younger generations imagine what one could accrue with the 16% FICA tax in stocks and bonds over a 30 to 40 year working career),
Then think of the U.S. Postal Service or Pentagon run procurement contracts with Congressmen interfering for their states and districts.
Unbelievable, there are those who now want the government to take over all health care with a government-run single-payer system with the promise that it will cut costs and improve health care. This is insanity!
