The polygomy being spoken of is not only men with multiple wives, but women with multiple husbands, and multiples of each with multiples of the other.
I'm not sure what "Low Status Male" has to do with the mix. A woman that would enter a multiple marriage for/because of money, which is what is being claimed, are the same women now that seek a monogomous marriage/relationship (or even quiet/side relationship) for/because of money. Either way, this woman is not going to end up with a Low or Mid Status Man. Monogomy/Pologymy, it's a wash.
In point of fact, Polygomy would OFFICIALLY get this type of woman off the market, and out of our (Low-Mid Level Status Men) way, not that we'd actually be frequenting the same night clubs anyway.
As a Mid-Low Status man, I was not interested in women with a primary interest in money. I needed a woman interested in geeeky, nerdy, quirky, and fun. Fortunately, High Status males aren't seeking that woman as a trophy, nor she him. So, polygomy wouldn't affect THIS search either.
Oh... there are plenty of "Low-Mid Status" women out there (a lot more than the "women will be victimized crowd want to admit) that would not want a #2 slot anywhere, but would be thrilled to be the one and only of a Low-Mid Status man that loved and treated her right.
As someone pointed out statistics that about 2% of people are wealthy enough, with various factors why not all of them would go polygomous, there would not be a heck of a lot of Polygomy going on. Further, (and again) we're not talking ancient patriarchical polygomy with harems, but polygomy were all of the parties must agree to it. I think a fair number of those "First Trophy Wives" have enough oomph to have a "Non Plural Marriage" clause in their contract, or find another man that will accept such a clause.
All the arguments against are women are too weak or dumb or greedy to function in their best interest. This is nonsense.
