People may be legitimately interested in finance, but it strains credulity to imagine that they would be equally interested if it paid as much as being a supermarket cashier.
I highly doubt those people are passionate about their line of work at any paygrade so this is a terrible comparison.
I'm not directly comparing the professions. Only the level of pay. It's laughable to think people would be as passionate about finance if finance paid very little.
I honestly see no problem with people who don't let their work define themselves and only go to make a good living, not because it's a passion of theirs.
