That could be a post-hoc-ergo-propter-hoc rationalization. Lobbying has gotten worse everywhere, politicians have gotten lazier and more corrupt everywhere. It's entirely possible that the term limits are not causal here.

I don't know what the solution is other than for all of society to treat politicians with utter contempt by default. Assume that they are selfish, incompetent social ladder climbers that will stab their constituents in the back the second it benefits themselves to do so. Do not let them back into polite society.

Unfortunately, I think the time when that would have been possible is long gone. The people in charge of the west have no shame and have all of the money and power they could ever want and don't need the approval of anybody outside of their incestuous circles to lead comfortable lives.
