Does anyone starve cities while playing Korea after reaching pop of 2 for xtra beakers. If you starve it down to 1 you will pick up an extra citizen. This doesn't seem to work if you try beyond 2 pop.
So you will essentially have 2 citizens available to work tiles at 1 pop, 3 at 2 pop, 4 at 3 pop, etc. You could unemploy these citizens for extra beakers or use them to work tiles. If you reach 3 pop and have a granary and water mill you could make 3 citizens unemployed for 6 beakers without starving. With 3 cities that is 18 beakers. If your capital is making a settler for a fifth city and say its pop is 4 then you could gain an additional 10 beakers by making them all unemployed.
