Why the difference between the excitement and opportunities in technology news and the horrible, terrible, depressing everything-falling-apart news in the political realm?

I challenge you to this experiment:

Spend a few days reading nothing but technology news. Then spend a few days reading nothing but political news. For the first few days [you will] see an exciting world of innovation and creativity where everything is getting better all the time. In the second period [you will] see a miserable world of cynicism and treachery where everything is falling apart.

Why is there such a gulf between those two worlds?
