My ex's parents were exactly like this. In a way I don't blame them as it's almost understandable that they have no clue how different everything from jobs to housing is these days.
But it was rather ridiculous them claiming to have never had a penny from the state despite both taking a state pension for many years, both had free university, having 3 children educated in state schools, complicated ongoing health issues treated by the NHS, surely took a family allowance and many other services they made use of but didn't for a second consider it a cost. The worst about working hard for every single penny was his mum, who gave up work not long after graduating to raise a family.
