There were many situations in the past 8 years, where laws could be passed to benefit High skilled immigrants. However Democrats always said that either you have Comprehensive Immigration Reform or nothing.
I worked with someone senior from FWD.us. Apparently it was created to make sure that there is unlimited H1 but no Green Cards (especially for Indians who are most impacted by this and are a decent part of workforce at FB, Google, MS etc). Apparently Democrats promised that they if they move their cause to support illegal immigration, Democrats would never let the Green Card situation get fixed for high skilled immigration. Due to this FWD.us completely shifted focus from high skilled immigration to illegals.

Am I right to say your argument boils down to the Democrats tent being too big for your liking, and you would prefer them to have catered to High Skilled Immigrants? Unfortunately for you, the Democratic party has been a "big tent" party since FDR - that's their political schtik. I think you should have expected more from the party that supports "job creators" like you (or maybe not quite like you).
You do have some Republicans who have some interesting things to say on immigration like Justin Amosh, but he's an exception. The nativists in the Republican party have been increasing in power an influence since 2010, and they want less overall immigration even among high skilled immigrants, it's literally part of their platform.
I would personally be in favor of scrapping the current system totally and setting a single cap per year. I would also give special consideration to refugees and skilled/in demand workers. I think increasing the number of temporary work visas is probably good as well. Now we have a cap per country, which is ridiculous.
The idea that the US always only accepted highly-skilled immigrants until very recently is false.
So US did get the best and brightest till recently!
In today's connected world and population explosion, there is a higher class of highly-skilled immigrants which can't stay in US, due to quotas based on country of birth. Because of this, best and brightest from India aren't moving to US anymore!
