As Milton Freidman observed, open borders and a welfare state are incompatible.
Libertarians are against border walls, and against government social welfare programs.
When faced with a strong welfare state, and the possibility of open borders, what does a Libertarian choose.
Some choose idealism first, some make a pragmatic decision, and say dismantle the welfare state, and the walls will come down.
In a void, Libertarians choose no borders, but the issue does not exist in a void. No Libertarian supports welfare expenditures for citizens, not for legal immigrants, and certainly not illegal residents.
Rand Paul is willing to have the government build border walls, if expenditures are cut in other areas.
Ron Paul and Rand Paul are two libertarians who do not support open borders, under the current state of affairs.
I find it interesting that there are two groups of immigrants, for all years, at all times. In discussion of immigrants, this distinction is often ignored.
Sometimes statements are made that only apply to one group or the other, but a blanket statement is made, that that pulls both groups together.
The problem is, “immigrants” may refer only to “legal immigrants”, or it may refer only to “illegal residents”, or it may refer to “all immigrants, regardless of legal status”. The terms are used interchangeably, with no explanations.
There are huge differences between these two groups, mostly having to do with education and skills, eligibility for social services, ability to be self sufficient from the moment of residency.
There are very few statistics for illegal residents using social welfare, yet no one denies that illegal residents are the payment name, and recipient of free HUD housing, receive food stamps, that feed the whole family, legal and illegal residents alike.
The illegal resident children go to school, get a free education, get free meals while at school, but no one knows how many children, how much money has been spent, because there are no statistics.
If 40% of a school district is on food stamps, all of the children get free meals and snacks, regardless of income, and regardless of residency status, legal or illegal. No one knows how much is spent on illegal residents, because there are no records available.
The cost to pay for
health care for
unauthorized immigrants is over $10 Billion per year. Nearly twice that, by some calculations.
Conservative estimates put the national cost of health care for all immigrants to be over
$36 billion per year. Total actual cost, with state share, etc, is likely twice that.
In a social welfare state such as the USA, there is a government cost for all immigrants, but most of that cost is for illegal residents, and most of those costs are hidden from the public. Libertarians are against all such expenditures, on principle.
The only way to prevent this unappreciated burden of paying for the needs of others, is to have secure borders. That is the position of pragmatic Libertarians.
