That seems disingenuous. This isn't about a few rich people's personal convenience. It's about lowering an absurd impediment to the creation of innovation and wealth.
The investors you mention must be really dumb to waste their time on foreign founders, let alone immigration reform, if they could just go and find better startups some other way. They say their bottleneck is the supply of good startups to invest in. Are they lying or incompetent?
