The term "rent seeking" as economists and the parent poster use it isn't about leases on apartments and offices per se, but rather capturing surplus- an example could be if you live in a house which requires leaves to be raked, your having more income might incentivize "big lawncare" to get laws passed saying you can only use a particular brand of rake in the city limits, one which can't be bought outright and has a monthly license fee attached.

The notion being put forward here is that the more money Joe Sixpack has, the more things will crop up to extract some.
