The federal budget comes primarily from personal and corporate income tax. Sure, there's a little bit from other sources like excise taxes, but those are a drop in the bucket.
Open borders means the US should make it trivial to get a tax id and work. Fundamentally, that's what people want to do anyway, work. Some people may get small handouts for food, or perhaps more expensive handouts for healthcare. The dominating factor by far is the infrastructure. good roads, reliable power, access to good food and clean water, contract enforcement. That stuff costs way way more than a $50 food stamp.
You'd be hard pressed to find an economist that thinks adding more people to the market makes the market worse. I understand the concerns about open borders, but making things so fabulously difficult is just blindingly stupid. If people want to come and work, it's literally better for everyone.
You seem to have a pretty good head for economics. Let me point you to my other comment in this thread for some more info on this important topic: https://news.ycombinator.com/item?id=9769632
