Sister was Laid Off Today

My sister has worked for her company for over twenty years in the PR department. Guess what? She was laid off today. Laid off after 20 years! Talk about being given the shaft. So now she's on the PR job search. Why wouldn't someone want her? She has over twenty years experience. Doesn't that stand for anything nowadays? I guess it's all about money. It's easier to pay less money for less experience. Personally I hope it blows up in her previous company's face.
