Considering that 1 USD is 49.5 INR, why does this come as a surprise to you? For context, 1000 USD will be around 49000 INR at current conversion(it will be less but for argument's sake) which is more than what a software engineer with 3 years of experience makes in a month.

I pay my maid 800 INR to do my dishes and clean the house. Manual labor in India is dirt cheap.

It's easy. Find a contract job in the US which allows you to work remotely from outside the US, move to a country where the currency conversion makes you rich and cost of living is low. Places like Singapore won't work - currency conversion doesn't buy you much, and cost of living is high.
