This is exactly why merit based legal immigration would push US back into the pole position, if it was done right. Lottery green card is basically a new way of excluding people from China and India from immigration, in the name of diversity.
Current situation for high skilled immigrants from India in US, is basically to cross the border to Canada, with it's amazing Express Entry scheme, which treats all immigrants the same, and evaluates each one based on the same scale (of education qualifications and work experience). Unlike the US, Canadian high skilled immigration rules don't discriminate based on country of birth!
My guess: In 10 years, Canada will be giving the US a tough competition for global VC spend
