Losing the chapter you joined?

[CRM114]

I never really considered myself to be the type of guy to join a fraternity, but when I came to my current school I wanted to broaden my horizons and get more social so I went out to rush. I found a small chapter that seemed to be full of a good mixture of guys who were close to each other. I pledged and was initiated and it was great at first. But a lot of the guys in the chapter are very ambitious and have pushed our house to get bigger. We've almost doubled membership, and as a result I feel the quality of our members and the chapter has dropped. I also feel like we've become one of the stereotypical "d-bag frats" that I hate, most of our members only care about partying and finding good connections with sororities. At rush, it seems that what connections a guy has or how rich his family is matters more than what type of guy he is. Should I just cut my losses and accept that I probably shouldn't have joined this chapter? I love the ideals of my fraternity but nobody else seems to care about them.
