I've said it tons of times, "free" markets do not exist, precisely because, to use your example, the US cannot decide what Mexico should or not do. So the only way, MAYBE, for the US to have a "free" market is to seal off boundaries with Mexico. Which is impossible and...would make that market not "free", since it would be protected by non-market boundaries. "Free" market is a myth.
of course no pure free market exists, that is obvious, but there are levels of openness
i dont understand what you mean that sealing the borders would make the us market free
i agree the us can not decide what mexico can do, but the us, mexico and canada can sit down and negotiate a treaty to control labor, just like they sat down and negotiated NAFTA to control goods and increase the level of openness, im just saying that ultimately that there should be a free labor market in the americas and just like NAFTA required all three countries to change their laws, a negotiated labor agreement would require all three countries to change their laws to match more
the only point im making is that i support a free market, but illegal immigration from mexico is not an example of a free market at work, its a highly distorted market and granting amnesty or increasing immigration doesnt help that distortion unless the countries the immigrants are coming from also are opening up their labor markets and their economies
How can immigrants bring down wages if there is a minimum wage? Either there isn't a minimum wage, meaning "free" marketeers are happy and let the market decide (and if someone wants to work for next to nothing, who can complain about that, if supply meats demand?), either there is a minimum wage and...somebody is employing those immigrants (are we talking about legal or illegal immigrants?) illegally, i.e under that minimum wage.
it brings it down because most people work for more than minimum wage
and its not just about a free market, there are negative social factors of having illegal immigrants working for less than minimum wage
Either way, if the immigrants are able to live and work in the US, it's that someone else benefits from the cheap labor. It's the same in Europe: no one wants to be the guy picking up the trash, yet they complain that immigrants "take away jobs from them".
everybody in every country complains about immigrants not just the us and europe
