In Europe its simple. Job offer above minimum salary? Apply and get a blue card yourself. Has been in the country for over 5 years and speak the language? You get citizenship.
In the US its nearly impossible to get a Green Card. Forget how difficult it is to get an H1B visa in the first place because of the lottery system.
The US is not responsible for that problem and never will be. And even if the US fixed its immigration inconveniences, the problem in India would remain.
India has other problems as well. For software engineers, the number one threat of hiring from India are the corporate cultures at Infosys, TCS and similar companies. I do not want to work with the alumni of those work cultures. It's radioactive-level toxicity.
H visa is not for world class top talent, that is the E visa.
