Because over time the threshold for the 'wealth tax' will be lowered until the middle-class are taxed out of their homes
I on the other hand with my $1 lower wealth am an average humble common man of the people.
A 35 year old doctor has a modest house and a decade or two of payments ahead of them.
A 55 year old doctor has long since paid off their house, it's a decent house and it's worth a few million bucks now.
Thus, viewed collectively the doctor class simultaneously despairs of ever owning a house, and owns a multi-million-dollar house.
Soon there'll be nothing left between the elite and the wage slaves/serfs.
