Why is that unethical? Someone will get that seat either way! It could make someone's day later on. I got accepted based on merit. I shouldn't have to feel bad about waiting extra time to decide. Plus one of those schools gets free money
oops...I meant "I would say it's unethical, BUT ... if law schools."
It forces more people to have to make more first deposits and wait later to make life choices. Some people cannot afford to engage in that game.
