If conventional current, is opposite of the electron flow, then is it true that ground doesn't necessarily dissipate charge, but is an unlimited source of electrons?

Ground is an infinite source or sink of charge carriers.

For example if you have a resistor with one node held at a potential +V and the other node grounded, the conventional current flows from the +V node to the ground node. If the free charge carriers are electrons (as would typically be the case), this means that your ground is acting as an electron source.

But repeat the exact same analysis with the +V node held at -V instead. Now the conventional current flows *from* ground *to* the -V node. Now your ground is acting as an electron sink.
