ok buddha--i'll bite.
basically--youre right.
here in the UK there are--what--100's of 1000's of over 70's in care homes. many are fully funded by the state--even though they own their own homes and have some savings. so--yes they are a drain on the economy.
the upside is the healthcare sector gives employment to at least the same number: a 20 bed care home could easily have more than that number of staff.
so if all those old folks give up the ghost there will be a corresponding rise in unemployment.
for the record--i'm 72, and am married to a much younger woman--who is the manager of a care home. aint i the lucky one.
