That's the drawback of continiously changing politicians. Such strategy is good in a short term, but will fail in a long term. When a politician could enrich himself knowing he will never be hold accountable and all shit he did will be left to the next similar self-enriching politician, then they will always choose such short-term shit.

So, politicians have to be hold accountable for any consequences of their decisions without any statute of limitation, even if they quit politics long ago.
