You need to stop watching whatever news outlets you are watching about migrants,. They are lying to you. The Migrants are all paying taxes through fake tax records or through sales taxes when they purchase items, but they can't get any of those social security, medicare, or other benefits back.
I have migrated in my life twice, and, trust me, I am able to distinguish lies, as well as have an idea what the real "tough migrant talks" are and what's going on in their communities. First - you wrote about faking tax records to pay taxes. How does that even make sense? People normally fake papers to NOT pay taxes, but doing it the other way around is something new. Second - in reality a minority of migrants are attracted by jobs, majority of them are attracted to welfare ("in the USA, they will give you an apartment! - Wow!", "you get food stamps - nice!", "there is free special medical card", etc.). I am not even mentioning wide-spread things in those communities like working for cash, and then collecting Section 8, Medicaid and food stamps. "Legal work for check? - Nuh, take your 'generous' offer elsewhere. Cash only please!".
Yes, there are some who say "I want to get a job to help family back home". But - European migration story shows that the primary motivation for migration is exactly welfare, not even war back home. Nobody from their migrants want to go to Poland or Baltic states, they all want to be in Germany, France or Northern Europe. And - only a small minority of those migrants are employed.
As for the debt. It is defensive spending'/wars that drive up the debts, also very piss poor financial managment by the GOP. This whole tax cut is only driving the deficit up. You can't keep paying for F-35 if you are only bringing in the income to pay for a corsair. If we were to cut out the "Entitlements" the US economy would collapse as the only thing funding the contiunued interest and budget deficits in defense is the very real taxes brough in by social security and medicaid.
Sure, I have mentioned we can't afford this defense, I am not arguing with you on this one. But even then, to be fair, you can't eliminate it completely. In 2019, we will have collected about $3.4 trillion in taxes, while having spent maybe 4.4 trillion. That's just north of a trillion of deficit. Another 800-900 billion are just to maintain the debt (yes, a quarter of collected taxes will go to treasury holders). Even if you zero out our national security expenses completely, you won't get balanced budget, but you probably can (and should) halve them. Yes, this will imply shutting down all foreign presence and ditching nearly all the allies, but the USA needs to sustain its economy somehow.
So back to my main question - even if you halve the defense expenditures, there is still 400-500 or so billion dollars of gap to close, if we keep the volume of help to those destitute as is. Where's the money for all this splendor? Gotta get to managing this splendor somehow.
The reality is that the greatest generation and their parents saw what happened when you don't take care of everyone.
And what about grandkids of those generations? You realize that they will pay with a lot of interest for this "care for everyone", paying an arm and a leg in taxes, having rather low living standard, making it do with inadequate and aged infrastructure, etc - right? If we don't want that - we gotta have a few hard conversations. "If you are coming to this country - sorry, you are not eligible for benefits until you qualify for citizenship and have worked for a few years". "If you are coming here for welfare - please don't", "Your family is in the middle class, but your grandparents are receiving food stamps and subsidized housing; it's time for you to pick up the responsibility for your grandparents, if you please. Society can no longer afford that", "you came here a while back, but the IRS still hasn't received any W2 from you. Perhaps this migration did not work out, please consider moving back to your country", "You have been living on Section 8 in San Francisco and haven't worked. Sorry, we understand it's a great city but we can't afford to pay your rent there any longer. Please consider moving to neighboring Nevada.". And such.
