This is fundamentally just a genre issue. Once you outpace the AI, well...You're describing symptoms of a bigger problem. Wack a mole isn't the issue. The issue is that once a player advances beyond a beginner the game offers zero chance of actually losing. The player no longer has to rely on his skill he just games the AI. After a certain point it kills playability for intermediate and advanced players. No challenge = no reason to continue playing. Yes, the AI doesn't run out of money but who cares because all they are capable of fielding is endless recruits that can easily be killed. The AI lacks any kind of meaningful challenge and has been reduced to nothing but a nuisance.
