Thats all.

Looking at this a little more deeply, the biggest issue is American labor is getting underpriced. What's causing that? Well, for starters there's the cost of an American education. The employee is looking at that as an investment and they expect a good ROI.

The second is inflated lifestyle expectations. That's been a big problem in America since the 90s. People aren't just living beyond their means, they're living well beyond their means - and just like the billionaires, they want more.

The result is we have recent college graduates expecting nice six-figure salaries. It's easy to offshore that. The growing trend now is to offshore to South America so you don't have to deal with the time zone shifts. You always have to remember there's someone a wee bit hungrier than you who is willing to work a wee bit more for a bit less. That's the person your employer wants.

This is what happens when you treat people like commodities, and you worship the market and money as your lord and savior.

India has 1/8th of the planets population. China is another 1/8th.

Obviously, Americans don't need H1B visas, and you are going to see more visa's coming from developing countries.

India's common language is English, they can easily communicate and get hired by American companies because of this.

Considering this, should it be a surprise they are such a significant part of the H1B program?

It isn't that 70% of the smartest people, though, they also have a great education system, it's 70% of the people that companies can assimilate into their environments are coming from India.

Perhaps the system could be overhauled to have an India specific visa and not group everyone in together?

Also, as a Canadian, another large immigrant population in the US, most of us don't come into the states under H1Bs because TN (and possibly other Visa's) are quite a bit easier.
