> those developers are not well paid (usually around 30/40 USD hour, no benefits)
$40/hour for a full time would put you just over the median household income for the US.
I suspect this provides quite a good living for their family and the devs doing the work feel like they’re well-paid.
I would love to see less pay inequality, but unfortunately, the median household in the US really doesn’t have it great due to the costs and risks of everyday life.
For comparison, I live in a place that is typically considered as tier 3 or 4 out of 4 in the US by employers (4 being the cheapest). Costs of living are honestly more like tier 2 cities, but it’s a small city in a poor state. 7 years ago, the going rate for an unlicensed handyman was $32/hour, often paid under the table in cash (I don’t have more recent numbers because I find DIY better and easier than hiring someone reliable).
