Yeah, someone with the public purse should have a much higher degree of accountability than someone who is spending their own money. In OP's examples, they were much less accountable.

In both public and private organizations the US suffers from people being less careful with other people's money or property than they would their own.

Is that not true generally of people regardless of where they live?

Certain cultures don't seem to be letting it run so out of control as to prevent them from getting anything done.

I think it can be made to have a high degree of accountability. There are a variety of budget approaches that can change the current nightmare.

I really like the Singapore model, where government employees are highly compensated, have built a culture of efficiency, and there are repercussions if they don't deliver.

and yet is the us the worst example what happens when healthcare is privatised. higher costs for patients, regardless for insurance; more sick people, because the go less to the doc for an check up and the highest prices for meds, because they are unregulated.
