decreasing the price of wheat would be better IMO. since the high prices of almost everything, for example iron has ruined those jobs in which you earn this exact resource (miners, waste manager, mechanic). meaning you can’t really earn that much iron by working since the earnlimit fills up so quickly and you have to wait for it to reset. so yeah IMO it’d be way better to decrease the max price of these resources since you really can’t stack up loads of any resource for later use for yourself. that’s coming from my own experience.
in short: I much rather have the ability to earn more resources at a cost of lower prices than the other way around.
