I don’t think that they have shrunk but they grew only moderately. When you account for costs like house no, health care or education then they definitely have shrunk. When I grew up there were families in my neighborhood with the dad working as a loader in a warehouse, stay at home mine, three kids and a nice house. This isn’t possible today. Even if lower incomes have grown a little, upper incomes have grown way more making a lot of things way more expensive for people with lower income.
