You sound like you're mocking it, and I almost didn't respond, but here goes (hoping you'll take this in good faith): people in the west like to nitpick on this, but you have to understand that Islam was born in an incredibly sexist environment where when your dad died, you could inherit your stepmothers as wives. Women weren't allowed to own property or inherit. So compared to that, Islam was incredibly progressive (women allowed to own businesses, inherit, entitled to all sorts of benefits in case of marriage, divorce, etc that simply did not exist before). So strictly speaking polygamy is allowed in Islam (man->women, not women->man) but that is not an obligation by any means. As times have changed, culture has changed, people have just stopped doing that as much.

I grew up in a conservative, Muslim-majority country and in my 18 years there, I did not meet a single person with multiple wives. I heard of one person though - a man from a village who worked in the city had one wife in each location. I never met this man, but a distant relative knew of him. That's it. Every other person I met was monogamous. I'm not trying to justify something you think is wrong, just giving you a bit of perspective that I hope you'll consider.
