I disagree, while financial aspect is important but it is not the only factor why folks choose these kind of lifestyles. First, having a kid these days might not actually be a good idea, with 7 billion people and counting, uncertaining future job market and the huge expense required to raise a functional kid in modern society. Previous generations never had those obligation or constrains and kids were able to contribute to their farms/income from early age. Second, technology allowed for lifestyles that were not even feasible in the past, it is really obvious and I don't think I need to elaborate on that. Last, humans were nomads settling. To sum up not everyone wants to live the mainstream lifestyle. So it could be due to preference and choice rather than financial pressures only.
