If there's a position, businesses expect it contributes to their profit. If the position pays $200k/yr, you can rest assured in the long run, they expect your work (or at least an average of your team, branch, etc. over that time) to produce at least what you're being paid in value. That's optimistically speaking but realistically speaking, more value must be produced than your total compensation (you're always worth more than you're being paid or compensated if a business is doing its job well). That's labor in general across the board ("skilled" or "unskilled").
The catch is when businesses overestimate a worker's value... that's when we plebeian workers are actually pulling money/value from the relationship--we're getting back more than we contribute in.
For some reason, culturally, this scenario for the laborer to pull more value than a business is taboo and seen as laziness, fraud, theft, etc. but it's somehow not taboo when the direction of the relationship changes: for a business to make money off its workers.
