Actually most of the patients that goes to a pte gp are covered by company's medical insurance.
Only minority pays from own pocket.
1. The rich leetired
2. The domestic worker
3. Children with rich parents and some of them the company also cover the immediate family.
Most of the time i see kiasu parents bring their kids there.
Occasionally domestic workers, as polyclinic charges for fdw is higher than pte gp.
I rarely see the rich leetired too
The rest are all those covered by company insurance.
Hence, majority of their earnings are from the insurance companies.
