Call it whatever you want, but if it isn't jealousy, I'd like to see you logically explain why you hold such contempt for these beginners. If they're not trying to be boastful or flashy, there's simply no reason for you to try to outperform them; they are probably well aware of their own skill level. As for a financial safety mechanism, I guess that makes sense, but if that was entirely true it would bring about genuine concern...not spite.
