Regarding Rush Limbaugh and contraception

Rush Limbaugh’s comments on contraception have shown that he doesn’t understand how people respond to basic economic situations. The contraceptive pill is something you have to take every day. You don’t only use it when you have sex. So if you think you might have sex once, you need to go on the pill and stay on it. This means that the cost of contraceptive pills purchased by the user is what economists call a sunk cost.
