Fighters are extremely good at accomplishing their single purpose in killing enemy aircraft. This is balanced because you cannot directly win games with fighters unless you shoot down a transporting ACU. Any unit with the ability to attack land units can actually win the game. Fighters can certainly kill all other air, but all other air has the potential to assault an ACU or economy(aside from spy planes). Even torpedo bombers can attack an enemy's Naval build power. Fighters could possibly kill an engineer transport to hurt economic growth, but it is hard to accomplish this at the early stage in the game when people are moving engineers from their few starting factories.
Even if your opponent has 20 ASF and you have no air units, you may be able to build other air units behind defenses or outside of their intel. Those units can be cleverly deployed to avoid enemy ASF or to strike a high value target while they themselves will almost certainly wreck.
As V said, defending against air is easy as you can simply build all ASF while they must build at least some non-ASF to hurt any of your economy or ACUs. Players win air dominance not because ASF are OP, but because they have better economy, micro, strategy, patience or another advantage. Equally matched players could constantly pitch equal numbers of ASF at each other and over many games come out relatively even. There is even a chance that the ASF will essentially cancel each other out with very few surviving on either side. ASF are not terribly OP if it all. If they were, a lesser skilled player could win consistently against a more highly skilled player simply by choosing to focus more on ASF. The better player will find a way to cost efficiently win the fight by building slightly less ASF and spending the resources on something to give them an edge. Cost efficient ground based AA comes to mind. At a certain point, it becomes extremely cost efficient to build some ability to deal area damage to enemy air. An example of this is how even CZAR(which has approximately less than half of its economic value dedicated to AA dps) can become optimal when ASF numbers reach a certain number. There are quite few other units with very good AOE vs air. Some are not very good at tracking fast moving t3, but they can still be used especially on a blob of targets which are turning around for another pass.
SAM are not guaranteed to win you an ASF war against most experienced opponents, nor is it intended to. It is also not supposed to guarantee the safety from air of even a single small base completely spammed by SAM in the late game. Enough strat bombers will always break through. Whether SAM can contribute to victory is entirely up to how it is utilized. It is hard to imagine SAM winning a game. Perhaps it could be the MVP if you placed it in range of your enemy's only t3 air factory to force them to halt production. There are easier ways to stop their ability to mass produce t3 air as this is probably not SAM's optimal purpose in most cases. I could certainly imagine being unable to breach a heavily defended base to destroy their factory, yet still being able to get SAM within range and protect it as your opponent has invested heavily in static defense to protect his factory. Cybran can even stealth in close to start placing SAM near their factory.
In short, I think SAM is balanced to be a good option to deal with a small number of t3/t4 air. If your opponent overbuilds all ASF, you can assault the factory on land or sea directly, or get SAM / other non air based AA in range of their factory to stop production of units which can hurt your army/navy.
I have a question about shields over an air factory. Will all air units produced from the factory be forced to leave the shield as they depart the factory? The idea of getting AA in range of a factory to destroy their follow up air-to-ground units to their ASF dominance would only work if those newly produced units were forced to fly out of a t3 shield and become vulnerable one at a time. A CZAR of course could still produce air within its hangar.
