As someone who is in the Emergency Services... It's not as simple as "Give more funding".
Trump cannot receive all the blame for the lack of a quality response, it's an issue that goes from top to bottom... From the training that personnel do every day, to the maintenance of vehicles and infrastructure, procurement of new tools, items, PPE... To even the more social side of things like advertising.
Which is precisely why I explained the current state of FEMA in the third-last paragraph, but it's Beloved Leader's responsibility to ensure that FEMA is properly staffed, trained, prepared, and equipped. He has clearly fallen short of that minimum standard by a wide margin.
That's part of Beloved Leader's actual job, so he should pull himself up by the bootstraps, take personal responsibility and do it already. The warning signs were there when he dragged his ass in appointing the head of the Agency.
You will also note I never proposed "more funding", though I did point out that his very first instinct was to defund them in areas necessary for FEMA to live up to its role effectively.
