I was wondering if the Buddha did give any advice on how to manage personal and/or society economics.

I assume that the advice would be the middle way as applied to everything else in Buddhism. To stay away from the extremes meaning e.g. spending all of ones money on one thing and instead divide ones amount of money in an equal way.

I remember once reading something about dividing one portion of ones money to food, bills, medicin etc., then one portion to enjoyment, then one portion to charity, then one portion to savings. Unfortunately i have no idea where i read it or if its actually really advice that came from the Buddha.

Thank you for your time.
