Older house wiring didn't always use a ground wire. It's acceptable to continue to use the older wiring, but if you update your wiring, anything that you improve must meet current wiring standards. You can replace a faulty light switch without updating the rest of the wiring, but if you bring the house up to modern standards it will improve the safety standards. If you can afford to upgrade your house wiring, the payoff will be worth it.
