They may find it's compulsory, as it is in Australia, where the state pension (SP) is means-tested.
And spending up your savings can be seen as deprivation of assets.
And your car, artwork, furniture are all assets to be weighed against the SP.
Oh, and when you downsize (to make room for the young 'uns who need the Boomer-tastic homes those fucking parasites have been occupying ) your pension will be reduced because you have made a profit.
Do I sound annoyed? Yes I fucking am.
