in the start i chose to kill the elderly and keep the young hardworking(big mistake) I noticed that workers and merchants pay you with creds but I still killed them off starting with the unemployed then the merchants then the workers, I began relying on farmers and kids. It worked out in the end as i ended up with 2 people and one ration a day due to one being a child and one being a farmer. Every day I would alternate who would eat in a schedule, sadly the kid died on the 22nd day and it was just me and the farmer
