I agree with education and healthcare tending to obscure the effects. In both cases, normal price sensitivity gets skewed because the person selecting which product they want (the patient, or student) isn't directly paying (because of insurance, or student loans/grants).
But there are plenty of service jobs that haven't seen big productivity gains. Masseuses, for example.
Almost all of them. Barbers, teachers, nurses... construction productivity in the US has collapsed. The US construction industry is literally less productive today than it was at any point in the last say 75 years.
