There's money to be had, but also a lot of money that has to be spent. Which is presumably why European countries/companies didn't develop a fifth gen fighter in the wake of the Cold War ending. Made some sense then, but now it's left them totally reliant on the US if they want a fifth gen (or better) fighter anytime soon.
