The Physics Police will arrest you for that one! A bad ground (or anything resistive in series with a load) will reduce the current through the load, not increase it. Bad grounds do not cause bulbs to burn out unless there is some other mechanism at work. I = V/R!
Corrosion where the bulb contacts the socket will gradually worsen due to environmental effects (primarily moisture) plus heat from the bulb as well as heat generated in the corrosion (which acts as a resistor). The corrosion gradually insulates the bulb from the socket until the bulb can no longer get enough current to run, but the bulb does not burn out.
