Elon Musk, the richest man in the world, did step up to help most especially by re-establishing communications with his Starlink technology. FEMA did its best to block his efforts. I think he finally did prevail.
He isn't the only one that has reported FEMA rejecting, even criminalizing at times, private efforts to help.
Again and again we hear reports of FEMA confiscating private donations and then taking credit for them if and when they are distributed. Do you think that is honorable?
Evenso many of the nation's wealthy have contributed to the effort. The MSM tends to give FEMA credit for everything though. Then again most of the MSM are nothing more than a propaganda machine for Democrats and cannot be trusted to report much of anything honestly.
