Our quality of life is definitely better than our parents and if all goes according to plan, our son's quality of life will be better than ours.
Our parents worked very hard for very low pay for many decades, in fact, my father couldn't afford to retire and died on his way to work at the age of 69. Both sides owned their own homes, but both had initially lived in their parents' homes for their first few married years in order to save the deposit. My OH's parents both died relatively young in their 70's and didn't really enjoy their retirement due to lack of money and poor health.
What we both have is work/saving ethic, so we ensured we got ourselves good jobs, saved like mad before we got married and bought our first home, and enjoyed a good quality of life, though never wasting money. Neither of us went to Uni, so we studied alongside full time jobs to get qualifications for fairly decent careers. We're now comfortably off and are starting to reduce our working hours in the hope of retiring early( maybe 60) as we've managed to save and invest in pensions etc (neither of us had occupational pensions).
We've instilled the work/savings ethic in our son, and all signs are that he will get very good GCSEs, go on to get good A levels, and then hopefully get a good degree from a good Uni, which will enable him to get a good profession, which will facilitate a decent lifestyle for him too. If there's any money left from our retirement, he'll get that too, but he won't need it if he gets a good profession and good salary.
I think we're one of the few families where each generation will have a better standard of living, but then again, neither us nor our parents really benefitted from the "boomer years" of plenty, i.e. no gold plated pensions, no buy to let properties, no endowment payouts, average sized homes which we still live in, etc.
