focus on doing comparatively more for comparatively less is dangerous

Second, that the NHS has a productivity problem; that it does not do enough with what it is given. This is to badly misunderstand the purpose of health care, which is not a factory for the sick, judged according to crude metrics of efficiency, but a service based on care, compassion, and quality. To continue to focus on doing comparatively more for comparatively less is dangerous and obviously harmful. Third, that the challenges faced by the NHS can be solved by drawing on a stronger private health sector.

Does "focus on doing comparatively more for comparatively less is dangerous" mean "focus on doing comparatively more (work for more patients) with comparatively less (care, compassion, and quality) is dangerous"?

No. They're talking about productivity. Efficiency. The "less" is resources. Money. Treat more patients for less money.
