Education costs money. But then so does ignorance.

Education costs money.  But then so does ignorance. - Sir Claus Moser

I would agree it's far more costly to be ignorant than it is to be educated.  To begin with there is the matter of employment.  People who are educated are far more capable of supporting themselves and their families.  While there is work for the ignorant, obviously it doesn't pay as well.  Further by definition ignorance is simply the state of being unaware or lacking knowledge.  That being the case, it would be easier to take advantage of one that is ignorant of labor laws or benefit packages for example than one who has been educated.  Being ignorant costs health care dollars and could cost expenses associated with accidents if one is unaware of certain labor laws that dictate how many consecutive hours they can work for that profession.  On the extreme end, if an individual or family cannot work due to lack of training, tax payer dollars support them.  Yes.  Education is costly but it's far better to be educated than ignorant.
