I don't think thats entirely true depending on what definition of farm is being used and where its located.

My grandparents live in Ukraine and do just fine growing most of their food on a small plot of land and their pension.

Tomatoes, cabbage, potatoes, watermelon, cucumbers, some other stuff I've forgotten and bees for honey.

They definitely do not have too much money on their hands. Time yes but thats no different then for anyone retiring?
