What you are describing would be ideal. Economic realities make it impractical.
We’re not rich, by any means.
When you do domestic stuff like cook your own meals, grow some of your own food, shop carefully, don’t waste money on buying more house than you can reasonably afford, eating out or buying prepared foods cause you’re too busy to cook yourself, daycare for the kids, movies, vacations you can’t afford, having to have the latest and greatest __________, mend etc, you CAN do it.
It’s not a matter of economic *realities*. The reality is, people can’t/don’t/won/t control their spending and live on a budget.
