I would have to agree. The "in general" though is carrying an enormous amount of weight in that statement.
I think what other commentors may be getting at is that in many cases the simple analogy of asking how 9 women can have a baby in 1 month is instructive here. You could throw trillions at that problem, a need to have a baby in 1 month. Sometimes there are hard limits that money has a hard time addressing.
A case could be made that with enough money put towards advanced technology, like gene therapy to force a fetus to maturity in 1 month vs 9, it could be done with horrendous side effects.
So to your point money does solve all problems, but I think diminishing returns is putting it very lightly.
