Explanation:
Let's examine all the answer choices provided.

Featherbedding consists on keeping on payroll more staff than you need, to create jobs or simply to respect a union contract.

That's when a company moves the fabrication of his product from country A (usually an expensive developed country) to a country B (usually an inexpensive developing country).

That's replacing machines by humans, could be for quality issues or to create jobs.

If you hire highly educated workers, you have to pay them more than unqualified untrained employees.
