Do Recording Studios Make Money?

I've come to the conclusion that recording studios don't really make money. I'm not about to discuss the actual numbers of what my place, Jackpot! Recording Studio, brings in and spends, but after almost three decades the truth is that owning a studio can feel a bit like performing a public service at times. I'm providing a place for others to make records while basically just covering the studio's bills. And I'm completely okay with that.
