Funny thing is where I'm from the Netherlands we even called it our golden century and still people can't connect the dots between our economic wealth and the plundering of the world. But I have already seen the break down of our institutions from 2008 till now, the shock of 2008 was so big that the dividend from western exploitation is not enough anymore to cover up bad leadership.
As long as there is generational poverty people from the imperial core will also carry generational guilt. The wrongs need to be corrected before westerners can talk about how to run things properly. But I don't see that happening until the western imperial empire breaks up into many pieces.
