To raise income, we have to produce more valuable goods or services.
We could also have people with higher productivity and income move in locally and spend some extra income locally.
If I get 10 well paid engineers to be located in a village of 1000 people and they start spending more of their income locally, it makes a meaningful difference quickly.
In the longer term, local skills grow and more village children aspire for high skilled jobs and learn the skills.
We could rebalance the village economy with just 1% of the population in high skilled jobs.
I hope other entrepreneurs try similar ideas. Find a village you love and please don't overcrowd the same place - there are 600K villages in India alone!
