Your justification of how you gain money from your investments via a wealth manager is similar to how a payday loansharking works, but you add the veneer of respectability by loan sharking to companies, not people.
Of course, that value that gets juggled around and ultimately disbursed to you is skimmed from underpaid employees and overcharged consumers, but so long as you get yours-that's ok. That's what capitalism is designed for. Your wealth manager works harder than you to provide you with a greater share of money, because you're on top of the pyramid.
If you're ok with how money(a measure of services or materials provided) gets into your hands absent any services or materials provided by you, it means you don't think too deeply about it, or you've just convinced yourself that you've somehow earned it.
