The US has a law that 80% or 85% of premiums needs to go to healthcare. So if an insurance company is already up against the limit, increasing the rejection rate will actually decrease salaries and yachts (because less money will be spent on healthcare, thus premiums need to be reduced, and the 20% available for employee salary becomes smaller).
Although, if increasing the rejection rate allows the insurance company to decrease individual premiums, which causes a lot more people to sign up for coverage due to low cost, that could increase total premium income, total spent on healthcare, and salaries.
