Compensation sentiment appears strongest when staffing is stable on strong client engagements and for market-aligned roles in major hubs.

Healthcare Strength — Healthcare coverage is often portrayed as a strong point in the U.S., with broad coverage and relatively favorable out-of-pocket experiences. Core medical, dental, and vision options are consistently described as meeting or exceeding a baseline expectation for consulting roles.
