When she was traveling she was doing it to earn income for her and her family. I know some people think she didn't need to work because they earn $75,000 per episode but maybe Kate was thinking about the future.. Maybe she thought that realistically the show couldn't go on much longer so she did speaking engagements to earn all she can now before all the opportunities disappeared. Just because she chose to work a lot doesn't mean she lied about missing her kids. What about working parents who have to travel? Do they not miss their kids?
Kate was home with the kids before and from what I understand, her traveling was only for a few months. I'm tired of Jon complaining about being stuck at home. Yes, he might not have liked being a stay at home parent but sometimes you have to make a compromise. For any couple that needs one parent to stay at home, what's wrong with having the parent with more earning power to work while the other stays home? If things changed and Jon had the earning power, Kate can stay home (which she did when he was working as an IT analyst). I'm curious, is Kate evil for traveling for work because she's a woman? Would people have the same perception if it was Jon who did the book tour instead?
