为什么有些工作薪资更高

Doctors earn more than cashiers not because one job is ‘better,’ but due to training and risk.
Medical school takes years, costs tens of thousands, and carries heavy responsibility.
Cashier roles require less formal education and have lower legal or health risks.
Markets reward rare skills highly—like coding or speaking five languages fluently.
Jobs with inconvenient hours, travel, or emotional stress often include higher pay or bonuses.
Location also matters—a teacher in Tokyo earns more than one in rural Laos, even with same duties.
Union contracts, company budgets, and local living costs all shape final salaries.
Pay differences reflect real trade-offs people make when choosing careers.
