How awful, Meglet. :(
As you say, Oblomov, depressing to see how many corrupt people there are, esp at the top.
The question is, is that symptomatic of widespread corruption across all levels of society? I hope not.
It could be rather that power corrupts, and hence those at the top are particularly corrupt. Or it could be, as I supect, that it is precisely those who are immoral/sociopathic to start with who seek huge piles of cash/power, as normal people don't need or wish to validate their lives by collecting unnecessary amounts of cash/power over others, and so end up super-wealthy/as top politicians etc.
If the latter, than the question is how to attract enough 'normal people' to positions of power and how to police the system so that the corruption is rooted out.
Certainly, in my own profession, i feel I am poor because I am left-wing rather than left-wing because I am poor (as is often assumed to be the case). If I was prepared to ignore my principles a bit more, I could easily make a packet. But I'm not. My principles matter more.
So rather than people being promoted to the level of their incompetence, as the peter principle claims, are people actually being promoted, in some cases at least (eg banks) to the level of their lack of principles?
