Whether or not uncontrolled immigration is beneficial to the economy as a whole depends on the context. In a free market capitalist economy, immigration means expanded supply of labor, which leads to increased division of labor, which leads to increased production, which leads to increased supply of goods and lower prices, which leads to higher standard of living for the average worker.
In a welfare state,unrestricted immigration leads to an increased burden on government subsidized programs, which leads to an increased burden and a genuine loss on the productive citizens already here.
Great comparison between free market and welfare economies.
I know very little about economics, but that is apparent even to me.
Throw in that the low paying stoop labor that immigrants used to perform has been done away with.
Farmers are using better farm equipment. Factories are using more efficient production equipment and methods.
Construction has become more efficient, doing away with the old pick and shovel.
The labor market has changed.
Companies are no longer looking for the unskilled laborer of yesteryear.
I guess Harvard University hasn’t caught on to that yet.
