You make the same mistake that the idiot CEO at Ford makes, that ADVERTISING isn't worth it. You know how you see all these Hyundai and Kia vehicles on the roads these days...that's advertising, even if per-vehicle the profits may not be great, they have a lot of vehicles on the roads, and that makes people more inclined to buy them. For all the Ford CARS that are not being sold, that's just giving that name recognition to other companies.
Ford still makes all those normal cars, they just don't sell them here in North America, so the R&D, for what it's worth, is still being spent. If Ford makes even $10 profit on a normal car, that's continual advertising for the Ford name that they won't be generating. These days, Ford vehicles are seen as yet more, "stupid slow bastards sitting in the fast lane doing 55 miles per hour in a 65 zone", and that makes people dislike the brand. Dodge is the worst for slow pickups in the fast lane, then GM/Chevy, and Ford is catching up to just being a name people link with inconsiderate drivers.
