<<<I'm not sure I understand this. Every analysis I have seen says that most immigrants contribute more in taxes than they cost (especially because they are not eligible for welfare, social security, etc.) and that by the second generation their children become fully 'Americanized'.>>>

Yes, you are correct it was the fact at one time, but fast forward to today, the past two years. Record amount of illegals are crossing our southern border at a alarming amount each day.

My intention here is to present the overwhelming amount of illegal border crossings each day.
So who is paying for the Security at the the Border? US tax dollars. Who is feeding, handing out warm clothing and blankets? US tax dollars. Who is busing, train and plane to other parts of the Country? US tax dollars. Churches and other organizations are doing what they can do to help, but they are overwhelm. Who are hiring the border crossers? I don't see the vast help wanted signs coming down. What skills do they have? Can they speak English?

'New Rule Makes Clear that Noncitizens Who Receive Health or Other Benefits to which they are Entitled Will Not Suffer Harmful Immigration Consequences'

'The final rule applies to noncitizens requesting admission to the U.S. or applying for lawful permanent residence (a 'green card') from within the U.S. When assessing whether a noncitizen is 'likely to become primarily dependent on the government for subsistence,' DHS will not penalize individuals who choose to access the vast majority of health-related benefits and other supplemental government services available to them, including most Medicaid benefits (except for long-term institutionalization ' such as residing in nursing home ' at government expense) and the Children's Health Insurance Program (CHIP). DHS will also not consider non-cash benefits provided by other government agencies including food and nutrition assistance such as the Supplemental Nutrition Assistance Program (SNAP): disaster assistance received under the Stafford Act: pandemic assistance: benefits received via a tax credit or deduction: and government pensions or other earned benefits. Receipt of cash-based benefits, such as Supplemental Security Income (SSI), Temporary Assistance for Needy Families (TANF), and other similar programs, will not automatically exclude an individual from admission or green card eligibility, and will instead be considered in a 'totality of the circumstances' analysis.'

Which is all well and good. Isn't this is what America is all about?
BUT....How do we take care of our own and the millions who have crossed into America and the millions more who will come if Title 42 goes away?
