In 1850, the average worker received 20 shillings a week or 240 pennies. Women received half as much. A worker received 960 pennies a month and could buy 1,920 baked potatoes on the street, 250-300 grams each, with his salary. I think raw potatoes were 3 times cheaper and a worker could buy 1,900 kilograms of potatoes. This is quite a lot, now in my country 1 kg of potatoes costs 0.5 - 0.7 $, but the salary in the province is about 400-500 $. Although a worker could buy more potatoes at that time, their housing was very expensive and many lived in cramped houses, clothes were also more expensive.
You have very low food expenses and quality vegetables. My own vegetables are enough for only half a year and I buy vegetables in the supermarket (of course they are worse than vegetables from my garden). For a family of 4, I try not to buy food daily for more than $ 10, but it is difficult. I spend $ 300-400 on food in the fall and spring, when I am in a big city.
