There doesn't seem to be much point in having a proper discussion with you though, as you aren't coming across as well-informed.
As has been pointed out, the economy is not like balancing a budget. There is enough money to pay people's pensions - it's just that it's not coming out of a piggy bank where their contributions have been stored for decades. Pensioners, on the whole, did not get furlough payments, many of them didn't get subsidised university places (and even with fees, most undergraduates are subsidised), they worked since they were teenagers and didn't get allowances for childcare or even maternity pay. Different generations have different challenges, and many pensioners are parents of young adults who are struggling with housing costs and so on. Some will leave inheritances to their Millenial and GenY children, too - I never hear friends say they are going to donate their inheritances to the poor, do you?
As a matter of interest, what exactly have you done to make the economy better for your children's generation? I'm not expecting the answer to be that you've done very much, as it's virtually impossible to do anything other than pay your taxes and not defraud the system. Much like today's pensioners, really.
