I don’t think money itself corrupts, but power does and power comes with money. Im currently reading a book “Human Kind” that argues that people are generally pretty decent, but that even a little bit of power almost always starts changing people’s behaviour, affecting their empathy, etc.
I’m not saying that the left is the correct side to drive on, but you do realise that roads and “driving” (with horses) have existed well before the modern car right?
In fact the US used to drive on the left, until large freight wagons started preferring the right due to where the dude holding the horse whip was sitting.
