Sir Winston Churchill supposedly asked Lady Astor whether she would sleep with him for five million pounds. She said she supposed she would. Then he asked whether she would sleep with him for only five pounds. She answered,"What do you think I am?" His response was, "We've already established that; we're merely haggling over price."- Marcus Felson, Crime and Everyday Life, Second Edition, 1998
We love to pretend humans have unflinching morals but they don't
There are people that wouldn't do it no matter the amount. Not for billions. Not for a trillion. And that's why no matter how rich the other party, there are people to whom they simply aren't rich enough.
"No" is the most powerful word in the dictionary. And when some people say no, they really mean no. And no amount of money can change that.
And most filthy, corrupt, bribed politicians and corrupt public servants out there know that fully well: they feel filthy and miserable because they know there are people out there with moral and ethics.
Additionally, there are people who honestly really don't give a fuck about money (it's not my case): so they'll say no not because of particularly high moral or high ethics, they'll say no just because they enjoy their simple life.
Honestly it's a sign of low moral and low ethics to believe that anyone can be bought out and that it's just about the amount.
Citation most definitely needed.
I agree with your ultimate point that some people can't be bought, and I aspire to be one of them - though I don't think anyone actually knows until they face a temptation with a life-changing upside - but spare me the "evil-doers are always punished, even if it's in ways we cannot see" rhetoric. Sociopaths, at least, are just fine (in fact show happier than the average person on standard "life satisfaction" metrics), and I'll put it to you that there are a lot of ways that both you and I don't perfectly live up to our highest ideals (do you own anything that's plausibly been manufactured by slave labor? Have you bothered to check? Or, if not that one, have you sold everything you own and given it to the poor?) and we both feel pretty good about ourselves, am I right?
I'm sorry. I really didn't mean to come at you that hard, but I'm going to leave it stand - it's not truly personal - because I think moral fables (ie, "do the right thing and you'll be happy") aren't true, and thus are counter-productive. Acting morally is hard, and often (usually?) comes at a personal cost. It's more honest to tell people that.
I think that’s a fallacy, too.
In my view we have some unflinching morals, some more flexible ones, and some you don't adhere to at all, and which is which tends to differ between people.
I personally don't believe in non-religious ontological good because of this aspect of human nature.
To be clear, I'm not making any claims about whether this is a large proportion or not, because I have absolutely no idea (and I have doubts this would even be possible to calculate with even a remote degree of confidence purely via philosophical discussion). If anything, some sort of study that provides evidence that this number is lower than expected would be a strong argument against typical "tough on crime" policies that are often popular with people who express concern about human nature in this regard.
The nuance you're looking for didn't exist.
