MIL looks down on me because of job
My MIL has always had issues with my job. I work a blue collar job and have for years. I make a decent income doing so and I enjoy my work. I seem to do ok because I'm doing a lot better than most people I know including MIL and her kids when it comes to money and other things. At family gatherings she will talk about my job (when people ask what I do) in a ways where she is making it sound more important than it is. She also makes negative remarks about "blue collar people." Some irony is that nearly everyone in her family including herself got their white collar jobs from somoene in the family they knew. Also most of them are in debt, have money issues or other issues. How to I address this without being extremely rude?
