This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again.

We all share one or more of these mindsets, and we start growing into them as soon as we are born.
