As lolinder stated, one of the main causes of this is Section 174 where software is now amortized as R&D over 5 years which means companies can't treat is as a regular expense. This leads to companies hiring less.

There is a bill that is stuck in the Senate which aims at reversing this (among other things): https://www.congress.gov/bill/118th-congress/house-bill/7024

Please reach out to your senators and tell them to support this bill so our job prospects can return to normal.
