Easy. "Kids, it's time you started paying me rent. Got no money? No problem. I got a lot of chores: cleaning the house, dishwashing, laundry, cooking, etc. Mummy and Daddy are off to catch some Pokemon or whatever."
Nope, totally wrong. The service you deliver to your children will far outweigh that rendered by them, at least in their youth. Inverse for renter / landlord.
All landlords reap far less than they sow. They are rentiers, they do not create wealth rather they exploit our regressive property laws to extract labour.
