In many areas of the US, this just means both parents work and have solidly middle-class (but by no means extravagant) incomes. My wife and I both work and we can cover the mortgage, all the expenses related to our kid, home ownership expenses, modest savings, etc. We are certainly not buying luxury cars or Gucci bags. Our big spends involve housing, healthcare costs, food costs.
I'm not sure who these people are who are affording discretionary purchases of hobby related stuff and luxury goods. That's probably more like the 1-2%. Either that or people are amassing debt so they can look the part and "keep up with the Joneses".
