So in reality you’re paying for their food, electricity and heat, letting them rent a room for free, and allowing them the use of the other facilities in your home and on top of that you’re giving them a spending allowance of 300 euro.

The marginal cost of food/electricity/bed for adding one additional person to a family is drastically less than those things would cost for a person living alone. Whichever way you slice this, the employer is making out like a bandit under this scheme.

In fact, you could do this for a homeless person today, in any city on the globe! And never even ask them to do anything for you!
