Possibly a cultural affect though? His statement could be true for the american context.

In a capitalism steeped melting pot, it does seem like things that might be more commonly 'seen'/appreciated in other cultures - pride in one's work, common standards of politeness, sense of serving/interacting with 'your community' rather than just 'anonymous strangers from other communities' - that could be non-financial motivators for good service elsewhere that are simply missing or too few & far between here.
