Serious scholars have examined what happens when we change the number of H1-B visas issued.
Cities that get more H1-B immigrants subsequently see the wages of natives *rise* substantially.
Skilled immigrants bring new ideas, fill labor shortages and make us all more productive.

Are there lawyers out there who have written about the most effective way to submit comments to government reports like the recent DOE one?

Please RT this so as many people see it as possible.

DOE climate report response form
We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me.
We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

We argue that climate clubs show promise:
- A climate club with coordinated penalties could curb 68% of excess emissions from free-riding
-Unilateral carbon tariffs? Not nearly as effective

We study how trade policy can reduce global emissions. Unilateral carbon border taxes have limited efficacy at cutting foreign emissions. By contrast, coordinated trade penalties under a climate club prove highly effective. buff.ly/NEE3Uy8

I'd love to fund studies of interventions that reduce real-time pollution exposure, in the US, on outcomes related to violence and criminal behavior.
(There is strong evidence that such exposure increases violence in real time; the next question is how much interventions can mitigate this effect.)

There are so many ways one could provide context for this data.
For example, in the last five years universities have received 52-55% of their research funding from the federal government. That's the lowest percentage since the 1950s. 1/x ncses.nsf.gov/surveys/high...

For decades, universities got billions in federal dollars for research. The relationship was mutually beneficial, until President Trump decided it wasn’t.

This framing is nuts, and the assumption is that public funding for a public good is somehow untoward and illicit. “The schools took the money” and became “warily beholden to the whims of politicians in Washington.”/1

Ok so yeah, this has quickly become the #1 misunderstanding about the canceled grants
the grants are not “subsidies” or “entitlements” to Harvard or Princeton or whatever
they aren’t going into universities’ endowments
they are competitive contracts won by these universities to do research

There is a PR narrative quickly emerging about “entitlement” of elite universities, as if this $ is some sort of subsidy
Harvard & others must counter this quickly
The $ doesn’t flow into Harvard’s coffers - this is grant money, most of which goes to research the govt has agreed has social value

I hope it doesn’t stop at redesigning websites & that other schools follow to defend their academic mission.
