We don't know what "people" want, but I do think that to whatever degree we can find such things out, we probably have a higher degree of confidence that the government doesn't want to iterate on the people who comprise it. The revolving door is a highly-valued feature in DC. That's what voting against incumbents threatens.
I'm not sure that your conclusion necessarily follows from your premise. We got a bunch of new people (mainly tea Party types) at the last Congressional election and if anything they've been more obstructive than the 111th Congress.
