A very wise teacher I once had has a motto: "That which you criticise, you cannot have." Empowerment coach, Tony Robblins, that I work with also says, "You will not consciously (and unconsciously) become that which you despise."
If you hate wealth and the walthy, you will never have money or wealth. You will never move towards becoming that which you hate or despise.
I see this mentality on a LOT of frugal/budget boards. I read them for tips and to find great sales. But, and undercurrent mentality is one of hating and disapproving people who actually
have money. Well, how are people going to get out of their own money problems when they hate the people who don't have them?
There is always an inherent disapproval of people who actually have money. Like, it's okay to struggle,
strive to save. It's even noble to scrimp, save, work
toward having money, like they're not taking food out of starving babies mouths. But when people actually mention they
have some money, those people get shot down.
OP, it's great you are aware and consciously wanting to work on your prejudices. When you get thenm handled, you may find the quality and money issues of your life change dramatically.

there are various money exercises, wealth /empowerment mentality seminars and trainings that really help wipe out old scarcity conditioning and belief patterns, because that's all it is, and
replace them with positive and empowering thoughts & beliefs about money, what money can actually do for people, ways it can be used for good, to help people, etc.
I have an arsenol list of
positive, wealthy, powerful people who have done great things on this planet. Having money was one of the tools to actually help them do it. My list grows all the time as I hear about new people and exdeavors or accomplishments. I don't focus on the negative people who do bad things with money, (like Bernie Madoff,) as there are
also many positive people out there, too. Like Warren Buffett, who donated
Billions to charity a few years ago to Bill & Melinda Gate's foundation. (Two other
billionaires.)
