Actually oversteer in a front wheel drive vehicle is every bit as easily (if not more easily) fixed with the throttle than it is in the RWD car.
The reason is becuase if a car is oversteering in the first place it's because the front tires are generating more traction in a lateral direction than the rears are. You can fix that two ways, either reduce the steering angle, reducing the turning force, or you can take traction off the front and add it to the rear. The way to do that is either get off the brakes if you were on them OR give it a little gas and whaddya know, it's not oversteering anymore.
But on a RWD car the oversteer is usually caused by too much throttle in the first place and you need to ease off the gas to regain rear traction, but if you jump off it too fast you do what you don't want, which is unload the rear tires, and around you go. If you got into the oversteer while on the brakes or otherwise off the throttle, the fix is the same as in a FWD car because physics is physics...you need to ease into the gas to get some weight to the back of the car. But in a RWD car it's easy to overdo it and make the situation worse.
Now to the general driver with no training, whose first instinct in ANY situation is to slam on the brakes, yes, a FWD oversteer condition is ugly but that's not to say it can't be fixed with the throttle, in fact that's the best fix.
