I've heard Sean Carroll answer the question: "Why don't more physicists worry about the foundations of Quantum Mechanics?" He said something like: "They first say they have no time, and it doesn't affect their work anyway." (kind of 'shut up and calculate' - Mermin, summarizing post-war physicists) "Then they imply that if they stopped their work and thought hard for 20 minutes they could solve all the problems." Maybe not original idea from Sean, but it rings true in my experience.
