I'm Romanian. We're not as bad as Mexic, in the sense we don't have drug lords and piles of bodies, but we definitely don't lose in corruption.
I've spent not a little time thinking about what can be done. I know the problem (pretty much everybody knows the problem) - politicians suck. They're either corrupt and incompetent, or just corrupt. Problem is, we really really don't have any alternatives. There is absolutely no party, not even a small youth one that's not the same. We can barely trust non-political watchdog organizations - hell, after the last elections we don't really trust them either.
The media is... ok. Private for the most part, and so heavily politicized (yes, it makes sense here), but they don't pull punches when it comes to criticizing the government. They're pretty open with both obvious mistakes and obvious cases of corruption - but the problem is, nothing ever comes out of it.
In a working democracy this would be a case for the justice system. Well, we have two problems. First, the whole system is also corrupt as hell. Second, it's also (probably on purpose) extremely inefficient. All the reforms in the past years, including a ridiculously publicized new constitution a few years back only made things worse.
So yes, I know what we need. We need:
* to respect the now largely ignored law saying that public institutions, education and health are non-politic;
* justice system reform
* new and fresh options for the next elections
* untainted public organizations
It's no mystery, really. The only problem is... how do we do it? It it my personal conviction that solving this chicken and egg problem is the next greatest challenge. A generic solution would be extremely useful for most developing countries, i.e. half the world right now.
