One thing I find worrying about arguments in favor of illegal immigration/very lax immigration policies is how easily it can come across as being in favor of indentured servitude and having a lower class to support the upper class. We say they do jobs "nobody else wants to do" for suboptimal wages, and they do it right because they fear what'll happen if they don't. And we proudly say that they contribute by paying taxes that support citizens while taking nothing in return.

You could honestly make a solid argument in favor of slavery using the same exact points. Go to a poor, dangerous country like Yemen, offer someone a contract saying they can live in a safe country so long as they accept that they get zero benefits, they'll be deported should they mess up their job, and a large portion of their income will support their citizens. Of course, this sounds terrible, because you're making them sign a contract and this is seen as taking advantage of them, when it's entirely their choice to go for it. But when no written contract is involved, we sweep it under the rug and even get people saying it's great because it boosts our economy.

Unfortunately there will always be those for whom this modern day slavery is better than the prospects they have at home.

You do them no favors by keeping them out because they never had access to "benefits" in the first place

I think this comes down to the contract really, and you could make an argument about many contracts which are not morally right (like marrying a 50 year old grandma on her death-bed and going away with all the inheritance. Is that right?). Sweeping under a rug will not be solved by banning immigration, or making it stricter, that would exclusively make it worse. Lax laws would actually tremendously help those kind of modern slaves. So i dont really see your point.
