Centuries of poverty turns into massive prosperity around the turn of the 19th century. The reason? The introduction of free markets. If you give people freedom and protect their property rights, what you get is massive prosperity. This is the *only* way to achieve prosperity.

They are migrating to work, not going to war. Ridiculous suggestion. And if we’re concerned about the break up of families, we can change our immigration laws so that they can immigrate together legally. Problem solved.
