In the real world, people often have to relocate to work for your particular company. So you're out $50,000 if they don't work out in the first two weeks and you fire them. Also, people that will work for you are working for you (rather than themselves) because they value stability. You owe it to them to get it right the first time.
(Also, at big companies, people cannot be fired. If you fire someone, their manager "loses an open" and they are less likely to get promoted. Remember, you have to deal with the bad employee, not your manager.)
