Is there anything wrong about making your mom quit her job because you believe you should take care of everything and she shouldn't lift a finger?

I really admire you and don't hear this often at all. While your heart is in the right place and your mother is probably working very hard sometimes the human species needs to feel needed. Being out in the workforce is a good thing and your mother may enjoy the camaraderie with her coworkers. People need to feel needed. Some women just don't want to stay home especially when their children are grown and out on their own or are self-sufficient. The best thing you can do is sit down and discuss this with your mother, but if she wants to keep her job then try to understand she needs it and jobs aren't always about money. Working also helps a person get over personal problems in their lives and if your mom is divorced she has a better chance of dating while working than sitting around at home. Women were meant to be more than just house cleaners and cooks, they are intelligent and your mother may be enjoying all of this in her work. Have that talk with her and if she doesn't want to quit work then respect her wishes and contribute what you want.
