My job is making me feeling like I'm helping the morally wrong

I hate resellers with a passion but today was it I'm just at a loss for words we had 2 of them at the ollies I work at and the first was personally nice , he bought $957 worth of ninja never stick pots and pans it came in a 3 and 4 pack boxes for $34.99.

First one he got over 20 of them it was the whole pallet we had and without realizing bragged that it's a great deal and he's gonna sell it for like $200 as they sell for $250 retail and I asked if it was an only positive thing as he can just return it and he chuckled and said he does all the time for things that don't sell well and how this is all he does for a living.

The second was a lady who witnessed the first guy after she already did her shopping (it's was $230ish of random things) and she bought the only other pallet we had as I was walking up to it to try and get one before they were all gone I rung her up and it was $627 or so and we had to load them into her truck but before that she said how she's gonna triple her money and how it was only a little 600 bucks and that I should get into it I told her honestly I haven't had a real dime to my name it like 3 months because of bills and rent and the bare bones essentials and her genuine response was that I need to hire myself a good money manager to sort that out and I'll be great and I just nodded and let her go.

They seriously don't understand what it's like to be poor like wtf di you mean money manager are you shiting be really your just a leach on society providing nothing for anyone just a ferocious for-profit middleman who ruin anything the second a poorer person can suddenly get the nice pots a pans they would love to have you buy literally all of them to sell for triple or more and brag about it.

It's just so disheartening to see this all the time.
