The most highest paying Jobs in the USA would be both Actors and Singers which can make millions of dollars per year but it's not really a job per say because singing is not all that hard if they have the talent.
But singing does require being on the road a lot and acting does require reading scripts and talent to do the job of acting correctly.
Other high paying jobs are Software Engineers that make around $100,000.00 per year or more in some places, A Physician who's salary is around $195,842.00 per year, Pharmacy Manager with an average annual salary of $146,412.00 and A Pharmacist with an average annual salary of $127,120.00
