Why does UX pay well?

Can you explain why user experience, or UX, professionals tend to be well-compensated in their field? Is it because of the critical role they play in shaping the overall user journey and enhancing customer satisfaction? Or is it due to the demand for skilled UX designers outpacing the supply of talent in the market? Additionally, do UX professionals' salaries reflect the value they bring to a product or service, and the impact they have on driving revenue and growth for companies? I'm curious to know the key factors that contribute to the attractive pay packages offered to UX professionals.
