Look in the mirror, that's who's responsible for this.
You people levied regulations. You levied them in half baked ways that resulted in the demise of sedans and station wagons. And now you complain that SUVs are "subsidized". Get out of here with that nonsense and take your stupid regulations with you so the rest of us can have diversity of vehicle choice back.
None of this stuff is a subsidy, construing "exempt from the screwing some other product category gets" is just a lie.
I had a Ford Focus wagon for quite some time, loved it. Cheap to buy, cheap to own, nothing exciting but very dependable and useful. With a small 4-cylinder engine it could not tow (at least not much) and rust eventually claimed it. Still ran like new with over 200K miles.
