I think we are in danger of confusing paying into a state pension scheme and then drawing benefits (the state pension) with a group of people who spend a significant part of their life taking from the system but not paying in or making much effort to pay in. (And there are also the other categories of people who pay in but need to take benefits at some stage or those who are genuinely unable to work through illness/disability or caring for others and need support from the state in a caring society.)
