Is it normal to look down on people like me?

Okay so I'm just really conflicted about this whole thing. It's so much, please bare with me. So you know how people say opposites attract? Well it's so true for me, but sometimes its not true for others. It all started with my first bf. We had a lot in common from how we were raised, our family, our values, which all contributed how we were both kind of privileged, not like rich but just privileged. During our relationship, (and yes I do feel sorta bad and guilty for this) I would always talk down to him because I just disliked about how he wasn't that hardworking, or not that street smart yet I lacked those, too. Its almost like I wanted someone opposite of me to motivate me and he just wasn't doing it. Anywho, we broke up and finally I met my current bf who is the complete opposite in that sense. We have been together for almost three years, and throughout it all, I realized how I sued to treat my ex and feel bad for it. I think because dating my current bf has highlighted the fact that I'm a huge hypocrite for looking down on my ex when sometimes my bf looks down on me for the same reasons. Yes, its totally karma.

So I thought I learned my lesson and I wouldn't look down on anyone again. Wrong. I recently met this guy and he reminds me so much of my ex. At first, it was just funny how much they're alike but then he just got on my nerves like my ex did, about how he's privileged and spoiled and doesn't really know his way around. It bothered me when it shouldn't. So recently I started treating him like I used to treat my ex, Ive been looking down on him and its bad. I need to stop but its just a natural reaction I have to people who remind me of well, me. I thought I learned my lesson but looks like I didn't. The bright side is I love my bf so much and one of the reasons why is cause he motivates me to work harder, and just be a better version of myself. So I do want to work on myself I mean it only makes sense if I just dont like people like me. But I def need to stop looking down on others who are basically like me, its so hypocritical but like said before, it feels natural to get irritated about it and thats why I think the saying "opposites attract" def applies to me. I wouldn't want to be with someone like me, lol.
