No we are very good at a lot of things. For example COFDM was invented here.
It is our government that is the problem. They are almost completely
controlled by special interest. The interest of the citizen is not even
being considered. Congresspersons have to spend all their time raising
money so that they can pay broadcasters for ad time.
Everything is condensed into the short term. What do I have to do today
to raise money for the next election. Their staffers do all the research
and in affect make policy for most items. Any Congressman can only be
personally involved with a few topics. The rest is dictated to him by
party demands and staffer input.
Not much hope of breaking this cycle. This is where a command economy
like China's can walk all over us. No messy democracy there. They are
now our bankers. Feeding us with cheap goods and loaning us back the
money so that our interest rates stay low and our houses go up and up in
price. Even Alan Greenspan is losing control of interest rates ( as if
he ever had any control). Alan can't figure why his raising short term
rates isn't affecting long term rates. Because China is now in control
Alan. Our future looks more like dancing to the dictates of a feuding
Asian threesome, S. Korea, Japan and China with China being our main
banker/landlord.
The next trillion dollar war the Republicans want to fight they will
have to go begging to these guys for the money.
