Thanks for starting this!
To say that IT folks have a higher order of skills is extremely mistaken. Many, many, many run test cases and do diffs, and even more create extremely simple code that barely works, with little design and "skill".
A good electrical contractor, or hardware guy who fixes motherboards, or a farmer who's able to maximize yield of cash crops from an acre, or a great architect often has a lot more skill and practical value, but does not benefit from the Dollar->Rs arbitrage in valuation currently.
On "earnings" - for one the valuation disparity at scale will reduce over time. I already know a great plumber who makes 40-50k a month. Then there is the issue of a wonky, inefficient, artificially expensive market that is chasing a small percentage of high earners making 30k a month seem "low". As more layoffs happen, and other skills become important and start getting priced better, or the artificial real estate component in pricing corrects, a lot of this will improve. There's also the issue of "earning" being multi-dimensional - often we get focused on the currency value alone. As market reality changes, many will consider lifestyles and entrepreneurship that create more time, health, community etc.
In fact if India has to get out of the jobless future we're staring at, we need to focus largely on micro-entrepreneurship that is pursued out of choice rather than desperation. Many a 6Lakh a year business can work a lot better than a handful of multi million dollar ones. And I suspect we need a large base of the former to sustain the latter.
