Uh, no. Both hurricanes taught the same lesson. The "Cajun Navy" (and later redneck auxiliaries) got their start with Katrina. A bunch of coonass swamp rats saw the failure of the government effort, and spontaneously came together to make it happen. They were a little better organized for the Baton Rouge flooding, and had it down to a "science" for Houston.

I noticed that we haven’t heard much from Schumer or Pelosi during this disaster

Different hurricanes, different lessons.

Katrina represented a failure of government at all levels even before the hurricane made landfall. Aging levees failed, pumping stations that were supposed to keep sections of the city dry were not maintained, etc. It was very much a failure of the city's infrastructure.

It appears that Houston was not a "failure of infrastructure" at all. The city was simply overwhelmed with a volume of rainfall that exceeded the design standards used for any storm water management system.
