The biggest shock my indian colleagues percieved when coming for few weeks into Europe - wow, you guys dont have home slaves err maids that you pay like half a dollar a day and abuse err 'employ' to no end? You actually clean your home, do the dirty parts of raising kids, do errands? Why are you living so poor? Their star-struck eyes about Switzerland very quickly sobered up, life aint a Bollywood movie.
I've spent 6 months backpacking all over india, seeing all the dirty underbelly some decade and half ago, interacting mostly with poor and poorer. Life-changing, extremely intense, beautiful and harsh experience. Those indians getting to the west are mostly from those top layers like brahmins, not your usual poor hard working common indians - 'american dream' is hard to achieve anywhere, but is nigh impossible there, regardless of talents and hard work put in. Everybody knows it, and profit from it as much as they can. Young brahmin couple telling me its fine that 5 year old kids work in fireworks factories instead of going to school, at least they bring some money home. Small kids with various medical situations begging on streets. Some sights and their utter unfairness still haunt me to this day.
I know damn well how extremely, ridiculously unfair indian society is, to the core, for millenias. Upper castes dont give a nanofraction of a fuck about poorer people, their suffering. Yes, you can live there like a king on IT salary, maybe not in central Bangalore or Pune, but India is bigger than Europe in more than 1 way.
Yet once you stop being poor, money is of little concern. Things like clean air, water and nature, safety, not having 50 C during summer, free good healthcare if not in US, free good education or social services are things we often take for granted, so do the immigrants over time. Life with some poor immitation of that is not that great, and it doesnt matter how high are the walls you build around yourself to shield yourself from the crap behind them, it simply ain't a great life.
So, comparing how much one earns, or saves is largely meaningless in longer scale. You decide which system overall you want to live in and often raise your kids, the rest are details.
