Fractal

A school where I was once a teacher,
two pupils' fathers were landlord
and tenant.  Furthermore, each father
was out of work and in discord.
The bank owned the house, the mortgagee
skimm'd the rent, the renter got money
from the State. He was frown'd upon,
although he receiv'd no soupcon
from this scheme.  Not an entrepreneur,
as is described a rentier.
Just dismissed as an envier
of the others unearn'd sinecure.
A vector to feed has to bite,
but he's not the true parasite.
