Use a long tapered punch from the opposite side. And use a heavy hammer, at least a pound. Hit it like it owes you money. One pop will loosen it enough to move the bearing spacer out of the way so you alternate hits, 180 degress apart. It will work it's way out. Use man tools, not a screwdriver and a lil' ball peen.
If that doesn't work, borrow your Mom's Dremel, buy some cutoff wheels for it and cut a groove, almost to the hub. Whack it hard with a chisel and that will relieve the stress and it will fall out. If you go a bit far and slice into the hub, sand the high points down before installing the new bearing.
You know how to install a bearing properly, right?
