Ethics of professional poker

Idk if this is where I should post those but wtf. This is an issue that's been getting to me more and more over years, and it's getting the point where I'm starting to question whether or not I can keep doing what I do and be ok with myself.

I've been playing for a living for a little over a decade now. For most of that time I didn't have any ethical problems with the predatory attitude necessary to maintain to ecosystem. This was largely because most of the fish id encounter were rec gamblers with disposable income who didn't mind losing. Over the past few years, though, I've been encountering a different type of fish more and more often. I'm talking about a gambling addict who's very possibly risking his kids college tuition. Obviously I can't be sure about anyones circumstances, but over time I've come to notice a level of desperation in certain players that's definitely not indicative of a hobbyist with disposable income.

I feel like I'm playing a part in ruining people's lives. Has anyone else struggled with this at all? It's no secret that gambling addiction is a serious thing. Of course there's the rationalizations like 'they would be losing to somebody no matter what, it may as well be me. ' that rationalization worked for me for a time, but face it - it's the same rationalization everyone who exploits others for personal gain uses. I'm wondering, how much is too much? If anyone else struggled with this, I'd like to know - how do you handle it? It's getting to a point where I'm considering a career change despite the fact that I'm doing perfectly well at the moment and have no other complaints so to speak.
