Not really. People tend to spend more on their hobbies (holidays, geek toys, etc) but it's not as if everyone's expected to spend their evenings snorting coke off expensive strippers.

From my experience people working in the financial sector are much more likely to be putting money into savings or investments than people outside the sector.

Presumably if your objective is to save money and you have some self control then it should not be too big an issue.
