I guess that DEI add some % of paperwork and costs, but it hardly a main problem or cause.

Google: chips act and dei.

Its not technically DEI , but if you tried to build a dam in the US some tribe would object it because (of course) that was the site of a sacred burial ground, or it would (allegedly) impact some specific animal that is sacred to them. Then CNN would rail about how the eminent domain "disproportionately affects PoC" and how "far-right congressman Badman voted to cut govbux to the poor women and children affected by this horrible infrastructure project".

Of course the energy company would only do it with liberal corporate welfare, awarded only on the condition of guaranteed DEI positions or strong preference toward subcontractors that were "women-owned " or Black owned.
