When politicians talk about tax and fairness, it's easy for them to point out undeserved loopholes benefiting the wealthy, or multinational companies. But the elephant in the room is the difference between those who own and those who rent (or have recently bought and have huge mortgages) the house they live in. The tax advantages of housing offend against justice on every count: they place financial stresses on the poor, they are unequal, and the increase in price is not deserved.
