The highest known paying job in the world would be a surgeon as they make around $258,000.00 per year and sometimes even $500,000.00 per year depending on location etc.
Well I really should say that being an actor or actress or singer is the highest paying job which it is but being a singer or actress or actor isn't as easy to get into as a surgeon or other job.
You can't just get a diploma and certification in college to be a singer as you need to actually have the vocal cords to be able to professionally sing and bring in the big bucks.
But some singers earn millions of dollars per year but you really have to have the talent.
Some great actors or actresses can also earn millions per year but most earn less than that.
