Jacob Horneberger explains what libertarians believe:
We believe that people should be free to engage in any occupation or profession without any government-issued license, permit, or other form of official permission. Let consumers, not the government, decide who engages in different lines of work.
We believe that people should be free to enter into mutually beneficial transactions with anyone else in the world, without interference by the government. That includes such things as hiring a housekeeper from Mexico and selling food to a Cuban.
We believe that people should be free to accumulate unlimited amounts of wealth and, equally important, to decide for themselves what to do with it — spend, save, invest, or donate it. Thus, we hold that people should be free to plan for their own retirement (or not), to donate to their church or other causes (or not), and to help out their elderly or ailing parents (or not).
