That’s a good list but don’t forget about the housing crash and recession of 08 right as we were finishing college
A lot of people ask me how I stay level headed with everything that’s happening like I didn’t grow up when Bush stole an election, failed to stop 9/11, launched two bullshit wars and Homeland Security, got caught doing straight up torture, and Katrina where Black people were abandoned & then hunted.
i don't want to hear your most boomer complaint. what's your most millennial complaint?

Chandra and Fermi also gone. Probes cancelled (so much work for nothing).
Hard to fathom why any sane person would do this, and hoping that there is a sane majority in Congress.

NASA budget would cancel dozens of science missions, lay off thousands
NASA released more details about its proposed fiscal year 2026 budget May 30, canceling dozens of science missions and cutting thousands of jobs.
