I don't begrudge pensioners and I certainly don't blame them that they have benefited in a way I never will. It's not a system they made. Whether it's unskilled, low paid manual work or a highly paid & skilled role, then the older generation had better luck.
Locally there are families where both parents work in the same warehouse their parents did. But they are desperately poor with pretty unpleasant, cramped homes. By comparison, only one of their parents worked and supported a sahp with a reasonable quality of life. The difference is social housing was easy to get and bought for peanuts, plus their parents got a low but secure wage. Now it's all zero hours and high private rent.
It isn't about resenting individuals, but about resenting the system/ society that caused it.
Only individuals I begrudge are those who refer to themselves as poor pensioners when they are comparatively wealthy, or those who think my generation just aren't trying hard enough, with no acknowledgement that things have changed.
I also find it hypocritical that when it comes to non means tested benefits the cost of administering is always given as a reason they should continue. But the same doesn't apply when it's working benefits.
Also agree with baby I'd prefer that money went where it was needed.
