I agree to disagree about this. To me, luxury is "opulence, luxuriousness, sumptuousness, grandeur, magnificence, splendor, lavishness, the lap of luxury, a bed of roses", and I don't associate those with typical developers. "Luxuriousness" is really a measure of
consumption anyway, rather than income, so it would entirely depend on how people
spend their money rather than how much they earn or receive. A big house, fast cars and yachts are
luxury items even if you had to borrow money to buy them. Having a good job is not a luxury because people with good jobs can still live ascetically.
Maybe this is just a cultural difference thing here. When I hear "luxury" I hear something like "extravagance" or "indulgence". Luxury is something you don't need and shouldn't feel entitled to. I think most people do need good jobs, respectful working conditions, good housing and time with their friends and family. I don't consider those to be luxuries, and I don't think that there's anything extravagant about those things. To me, this just highlights how truly awful it is that most people do not have these things.
