Maybe some sort of trickle down effect from the money that goes into Amazon, intel, MS & IBM.
Not sure every home in the US is getting the claimed 10gig internet pipes neither.
The government - university partnerships have been a massive boon to the US tech industry.
They have billions in business grants that you can apply for, covering just about everything you can think of going on in the economy. That includes advanced science and engineering grants, projects at the most cutting edge.
Every home is definitely not getting 10gbps pipes, yet. The US deserves a lot of flack for its poor broadband deployment the prior decade. However it is now undergoing an accelerating broadband boom (as in 100mbps+), probably mostly thanks to Google.
