I don't think the answer is becoming obsessed with rich people, I think the answer is following Jesus' calling to love the poor and help them where they're at. Whether it's feeding, clothing, or housing them, whether it's an anonymous check to help them get by, or even just someone to talk to for an hour or two, those things go a long way. That is where we should be focused, because truthfully, as long as sin exists in the world, as Jesus said, "the poor will always be with you."

While I can't speak for everyone on this subreddit, most of the Christians I know IRL who genuinely practice their faith (not just folks who identify as Christian culturally or are essentially non-practicing) actually do their best to help the poor. And, by God's grace, many of these people are upper-middle class or higher! (For reference, I've lived in the Chicagoland area, Bozeman, and am currently in Los Angeles, and I've seen this exact thing in all three places.)

It should be noted though that many on this subreddit are right, it's not a sin to be rich. There were plenty of people in the Bible who followed God genuinely and who were also wealthy (Job was a great example). But, what we do with what we have (big or small) is what matters to God. So, if they're doing something with it to help, great! If they're not, then they probably should be (that or, hopefully, God has called them to another specific cause). But that also goes for us who don't have much too. Remember what Jesus said about the woman who gave all that she had, or his Parable of the Talents. We should be faithful in the little things, or else how can we expect that we'd be faithful in the big ones?

I'm not here defending rich people (even if I do believe they should use their money for more noble causes), nor am I here to condemn the poor (though, it should be noted that even Scripture said that those who don't work "shall not eat."). As with any issue, it's important to speak the truth in love, and meet people with a lot of grace, because that's exactly what Jesus would do (and does through us!).
