"I paid for my home out of taxed income!", i.e. so it's unfair to tax me again on its rental value.
Kj knocked this one out of the park a couple of days ago:
"In the parts of the world where we have mortgage interest deductions, the argument "bought my house out of taxed income" falls entirely flat, unless you bought it with saved cash of course."
We had full mortgage interest relief in the UK until the late 1980s, so anybody who bought their home before 1970 or so and/or had paid off their mortgage by 1990 or so actually bought it out of tax-free income. If they try using the argument you can just call them lying bastards to their faces.
The relief (called MIRAS) was phased out gradually between the late 1980s and 2000 or so, but most people who bought since 2000 or thereabouts probably haven't paid off their mortgage yet.
