My gut instinct is to agree with you, and contribute the truism "you get the government you deserve".
If people are dissatisfied, I think they need to vote fringe - whatever party YOU think will represent you, or at least send a message to the incumbents. Sure, none of them are going to get elected, at least not anytime soon, but you have exactly one vote. For all the difference it makes, you may as well cast it with your conscience.
Enough people do it, change will happen*
*not withstanding any "errors" introduced by those fantastic electronic voting machines...
