Why does it not make sense? Imagine you have factory workers making 15$ an hour and a company decides to import labor to work at 10$ an hour because there’s “no limits” to immigration. The government should act in the interests of its citizens.
It's in the interest of citizens to get their goods at the cheapest price. Thats why you have imports, which is no less than importing the produce of labor.
With people, you have the added benefit that if people working within your country they spend and consume in your country.
Countries all over the world fight each other for talent, and the US immigration system is doing to itself what other countries spend money to prevent.
