People grew wheat, it was taken to the mill, each house or village had a communal bread oven; bread was made and sold or traded. The wheat was grown without chemicals or motorised transport and without destroying vast tracts of land. Clothes were made by hand or basic machinery; vegetables and fruits grown by each household if they had land. People knew how to make things - baskets, shoes, saddles, roofs, carts, churches, goat pens, pottery, lace, knitted socks, bottled fruit, candles; and how to do real survival things like killing, skinning and cooking an animal, gathering plants - and knowing what was edible or not, fishing - without half a shop full of latest rod and tackle equipment - and a thousand other vital things.
No doubt this is highly simplistic and of course life would have been hard in many ways but a five minute glance through the current news seems to prove that we have learned so little in the last few decades, and lost so much. Thank the lord of handed down crafts that there are still some folk who know how to make and repair everyday and vital things, and rejoice in doing so. Hopefully as kids reach the age now of deciding their futures, basic and real skills will once again be offered and encouraged in this rapidly changing and climatically unbalanced world.
