Max, I think the situation where you have, say, a charged ball and connect to ground, then electrons can move from the ball to earth. (This basically happens because the ball is charged with respect to earth).
But in a charged capacitor, whether a battery is connected or not, the situation is different. The negative pole of the capacitor has an excess of electrons, sure, but they are being held there by the 'positive charge' (to simplify things) on the other plate. In other words, a charged cap, connected to nothing (or a battery) is in equilibrium.
If you connect the - to earth then nothing will flow into the earth - if any current (ie electrons) *did* flow then this would disturb the equilibrium on the cap, which would immediately suck the electrons back to the plate. (Which is precisely why they won't flow).
