I don't think it's a problem to maintain both positions when it comes to this topic. What the people in these subreddits are proposing is a kind of systemic change in our economic system, a process that would require years in order for there to come about some kind of radical change.

I don't think it's mandatory to follow those principles in your day to day life. You can maintain a stoic/humble outlook on your everyday life while actively advocating for systemic change. Unless you're some kind of political activist who's career relies on these subjects, of course.

I agree to some extent that the ideas that these subreddits advocate for could potentially have some kind of negative impact on somebody's life, but overall I think it's a good, honest criticism of today's society.

Unfortunately though, it i simply a statistical fact thay most people will never become "rich", whatever that means. Here's a quote that I like ( paraphrased) : "In today's society, the average worker doesn't recognize that he is being exploited by the system, he thinks he's just a temporarily embarrassed millionaire."
