the Republican guest on Crossfire last night talking about how the messed up roll out of Obamacare shows that Government can't do things properly. I wanted to reach in there and grab the guy by the scruff of the neck. This ACA roll out fiasco is the private contracters fault.

I'm pissed

Well, private contractors, nearly indentured Chinese immigrants, and other unfortunates.

Government can and should do big things. Rarely can government do it without help. I look on government in this role as a convenor or facilitator.

when it has done things no one in the private sector could deliver.

That's basically just not true; it was private contractors. Glad to see there's room in your thinking for help no matter what the form is.

Of course the government can deliver things the private sector cannot. Only the US government has the power of the US Treasury behind it. That helps to kick a lot of ass. There's a reason the US put a man on the moon first.

It was built on government land, over a government route, with government subsidies.
From wikipedia

But that's a completely different assertion than "built by the government" and also acknowledges that public/private cooperation can (quite literally) move mountains. And again, as it hits close to home, let's not forget the thousands of Chinese immigrants used to build the Western portions.

they and their ilk unleashed on the world.

Meanwhile here's the 2013 Report Card for America's Infrastructure from the ASCE

<snip>
Over two hundred million trips are taken daily across deficient bridges in the nation’s 102 largest metropolitan regions. In total, one in nine of the nation’s bridges are rated as structurally deficient, while the average age of the nation’s 607,380 bridges is currently 42 years. The Federal Highway Administration (FHWA) estimates that to eliminate the nation’s bridge deficient backlog by 2028, we would need to invest $20.5 billion annually, while only $12.8 billion is being spent currently. The challenge for federal, state, and local governments is to increase bridge investments by $8 billion annually to address the identified $76 billion in needs for deficient bridges across the United States.

The government funded many of the first 6 on your list, but the implementation of all was done by private firms.
