I think you’d have had zero problems having engineers on the GS scale prior to November 6th, 2024. No, they wouldn’t get rich but it’s a space full of interesting technical and usability challenges and you’d be able to work on incredibly high-impact open source projects. Like if you simply make it easier for someone older/disabled/etc. to fill out forms, make good security decisions, find information, etc. literally millions of people benefit from that a couple of weeks later.
It’d be neat if the EU picked up the torch here but with any government it seems like it’d be better to have a non-profit get a block grant so you avoid things like those salary issues or other challenges: for example, if the EU decided they didn’t want to depend on the U.S. for critical infrastructure, funding a back-to-its-roots Mozilla.org would make it easier for, say, Canada or India to join in without the issues you’d have trying to directly pay government employee salaries.
