I can see how that might be true in general, but would it really apply here? Even at my most cynical, I have a hard time believing a contractor would be so careless about Notre Dame, a major national symbol.
Firstly, calling Notre Dame a National symbol is a bit exaggerated. Honestly, for a lot of French not living in Paris, Notre Dame is just another Cathedral with a lot of advertisement because its Paris (France/French relationship with Paris is ... complicated).
Secondly, yes, most contractor focus on money, not really doing the best job they can (I mean, in many way, the fire is a proof of this).
I work for, arguably, one of the most critical French industry. One that France rely on for security and, somewhat, energy. Some of the worker were proud of doing something for their country, but the decision from higher-ups were purely financial. And it is what is expected from them to be honest.
