Lots of jobs have physical limitations that mean you do not keep working until retirement age.
In those cases you know in advance this will happen and you plan accordingly. Put money aside for property purchase and retraining. It is what footballers did in the past as several posts on this thread explain and what lower division players still need to do.
As it is the top players have annual remuneration packages of 10s of millions of £, plus money from sponsorships and cuts of their transfer fees. There are still big corporations, lareg private companies and the like who's CEOs are on less than a £million and most, perhaps not the CEO of Persimmon, probably earn less than a top name footballer.
