Well we're talking about blue-collar vs white-collar, so naturally I'm painting with broad strokes here, and this is all anecdotal. In my experience the people who have tried to hold me back from my objectives the most have come from blue-collar backgrounds. I'm not saying that everyone I've met from a blue-collar background has done so, just that of the people who have done so most have been from blue-collar backgrounds.

And come to think of it the financial reasons you mention (retirement) is probably one contributing factor from a cultural perspective. If you lack the independent wealth to look after your own interests then you must naturally pool resources with others. If others leave/do their own thing/do better than you that's saying, in a sense, that they don't want to pool resources with you, even if you'd reciprocate. That feeling probably sucks.

On the other hand if you're well off enough on your own, someone going off and doing their own thing/striving for better isn't a rejection or a denial of needed resources. So it can be supported, event celebrated.

Once again, painting with broad strokes. It is possible to point out trends without saying that everyone in a given group subscribes to said trend.
