This is just a side point, but:

> We have much more control over how we hire mathematicians, publish papers, and train students than over the behavior of trillion-dollar companies, and that is where our efforts would be better spent.

We should also make sure that there are no trillion-dollar companies. The existence of large and powerful companies is a problem, whether or not the field of mathematics is in crisis. All these companies should be shattered so that they cannot do things until after society as a whole is sure they're okay with those things.
