I'm sitting on $200 billion and can't spend it. My syndicate is maxed on bonuses and has a healthy bank, I am filled on the strongest money weapons. The new LTB will cost only about $40 billion for full upgrades on two. I make that in less than four days.
I currently can upgrade four buildings at the same time. Even if I upgrade the 4 most expensive LTBs at the same time I'd still end the cycle with over $100 billion extra. Let's get another upgrade modifier.
