Will the US economy collapse again in the future?

I would predict late 2010-early 2011

Unemployment and government expenses will catch up with the artificially stimulated economy and you will see a worse economy than the great depression.

The government isn't making it very easy for the private sector to function by giving unions more power, and by raising taxes/control over private sector businesses. The government stepping into the private sector will also cause the private sector to suffer by creating competition and higher regulations.

It's going to happen, the question is when...
