i don't think it does mean that someone who never worked and someone who slogged for 50 years end up the same. the slogger will have their own home, full state pension and whatever pension they paid into in those 50 years. they will have options like releasing equity or renting out their home whilst they travel or go to live overseas, they will have the ability to leave an inheritance to their children etc.
the theoretical never worked person will likely be in a council flat (bedroom tax isn't going anywhere) living on pension credit with zero capital, zero options, zero credit facility and zero chance of going on holiday let alone going to live overseas or leaving money to their children.
it's a falsity to say it doesn't pay to work, they've got everything we've got and they've never worked a day in their lives.
having your own home, choices, a car, the ability to go on holiday or travel, leave money to your children, treat the grandkids, go out for meals and take up leisure pursuits etc really IS something and is worth working for surely?
would we really see that as on a par with a pensioner with nothing to their name but woohoo they've got a roof over their heads and so long as winter doesn't get too cold or last too long they'll hopefully not freeze to death?
