I’d echo what the others have said re: pay and flexibility and add another point-

Autonomy and Impact- people need to feel like they own their work and that it matters to someone. Meaningful (subjectively defined) work is an important motivator in my experience. Creeping nihilism erodes morale and motivation.

I’ve found that nihilism is often caused by broken processes that fail to fix obvious deficiencies, especially in large corporations. This ranges from pointless hoop-jumping to get simple software packages to the lack of accountability/oversight for low-performers and everything in between.
