I work for a corporation. I know lots of people that do. We are essential to keeping things going. Someone has to work for the companies. People would freak out if they walked into their bank and it was just a line of ATM's or into a McDonalds and were faced with vending machines. There isn't anything wrong with being the employee of a large corporation, and for lots of people they are very satisfied doing so.
But know this - the corporation doesn't care if you don't get to spend time with your family. It doesn't care if you don't have time to work out or read or do other things that are good for you and your family. It doesn't care, it can't. You are one of many mice on a wheel - there is cheese to keep you going but don't expect more than that. One cannot become truly wealthy working for a large corporation. Sure, the corporate job can be a means to and end, a way to get to your real goals, but expect them to keep you hungry so you continue to chase that cheese. The rules can change at any time and you MUST accept it or a new mouse will take over your wheel and you'll be without.
