I would like to teach online full time. Would it be worth it financially to earn a Phd? I know that it is a ton of work to earn a PhD and you may see the money earned as not worth the time spent, basically all I want to know is if I earn a PhD will I make very much more money teaching online? Second, does it matter where I get the degree from, Walden, Capella or Nova? Are they all the same or is one looked upon better then others?
