In the US, C-sections reimburse higher than vaginal deliveries across the board. What's changed over the years is who gets the extra money from the C-section. It used to be the physician, but nowadays it is increasingly the hospital. The incentive to do C-sections over vaginal deliveries is still there, but it's transforming into a population level incentive (i.e. is the hospital structuring staffing and workflow in a way that favors C-sections) rather than an individual one (i.e. is a particular physician very trigger happy with C-sections in a way that happens to line their pockets).
