Quote #1
Between the pride and intellectuality of his mother and the sensuality and irresponsibility of his father, poor Prince Fabrizio lived in perpetual discontent under his Jovelike frown, watching the ruin of his own class and his own inheritance without ever making, still less wanting to make, any move toward saving it. (1.12)
Fabrizio sees his entire social class collapsing, but doesn't feel like doing anything to stop it. In his mind, there might not be much about people like himself that's worth protecting.
Quote #2
And thus eventually it cancelled itself out; this wealth which had achieved its object was composed now only of essential oils—and, like essential oils, it soon evaporated. (1.90)
Fabrizio has been wealthy since the day he was born, so it makes sense that he doesn't care all that much about money. He knows that his family's money is going to disappear with time, but doesn't do anything to stop it because he figures there's no point.
Quote #3
Don Fabrizio, in fact, could not see what else there was to do: whether treating it as a fait accompli or as an act merely theatrical and banal, whether taking it as a historical necessity or considering the trouble these humble folk might get into if their negative attitude were known. (3.25)
Fabrizio advises all of the people in Donnafugata to vote "yes" for Sicily to join Italy, even though this will strip him of any royal status. He does this for several reasons. Two of the main ones are: 1) because it's going to happen either way, and 2) because he doesn't want any of his friends getting into trouble with the new government by voting "no."
