I know how easily things on the internet can seem like debate when it's just a calm discussion. I was just curious to know more about your position, which you've provided. Thanks! I don't think there's much danger of any of that, but if there was, I agree that it would be a bad thing.
The only people I could see acting that way would have to be classist jerks, so I wouldn't want to play with them anyway. I know every group that I've ever played with (including many hundreds of players at my store) have been of an extremely wide variety of financial stability. I've met a few difficult jerks over the years, but I've never met anyone who held anything at all over the other players in that sort of way, thankfully.
Hopefully your fears will never come to pass (in the very least in any widespread way!)
