When last we heard, the caravans of rabid child rapists and their drug-dealing mothers were almost at our southern border, to which our gallant troops had rushed to make a last desperate defense of the homeland against this pestilential invasion. That was, what? six months ago? Just before the election, as I recall. Time to get an update on the migration invasions.

Here’s one the Trumpits haven’t blown about: thousands of desperate people — 6,000 every per day at just one crossing point in Yuma, Arizona — swarming across our southern border in search of help. These people represent an existential threat to the US economy, yet the troops already deployed to the border have not been used to stop them.

But wait, there’s more. An organized caravan of migrants on a 600-mile trek across our northern border, all of them intent on wrecking our economy and soaking up free socialistic benefits. Where, you might ask, is the wall that could put a stop to this?

Couple of interesting details. That southern migration, the one that just at Yuma involves five times as many refugees per month as came into the United States from Mexico last year, is going south. Into Mexico. Specifically, to Los Algodones, a city that has turned itself into an enormous dental clinic to serve desperate Americans who can’t afford dental care n their own country. Locals and visitors alike have come to call it “Molar City.”

There are more dentists per capita in Los Algodones than anywhere in the world, and there’s still room for pharmacies and vision-care specialists, all charging about one-third what Americans have to pay in their own country. Nearly a quarter of US residents have no dental insurance, and those who have it find it extremely limited — most are capped at $1500 a year, which typically will not pay for a single crown.

Mexican dentists have no student-loan burdens — their education is free — and they are not required to carry malpractice insurance, and they don’t have to spend their days wrangling over the phone with insurance idiots trying to avoid paying benefits. As a result, a human tide of dental refugees who should be supporting American free enterprise are giving their money to Mexico. They must be stopped.

About that northern caravan. It also crossed our border going the wrong way — into Canada — and it also should draw the attention of the Trumpits because it is all about bringing drugs into the country. It was made up of people who have Type 1 Diabetes and cannot afford to buy the insulin they need in this country. A vial of insulin — 1,000 units, enough for a week to ten days — from an American drug store typically costs $300. The identical dose in Canada costs $30. The cost of production is estimated at $10.

In 20 years, the cost of insulin has spiked 1,100% in the US, for no apparent reason. This does not seem to have happened in any other country inthe world. Then there’s the contribution of the lucrative insurance industry:

“This year it took me 15 phone calls to a variety of parts of the healthcare system over 11 days before I could get my daughter’s insulin refilled. And this is exactly the same insulin we’ve been getting for many years,” one member of the Caravan told Newsweek. “But, in Canada, you just walk in and you buy it. It’s literally just as easy as, you know, walking up to the pharmacy counter and asking for what you need.”

So there you have it. Canada and Mexico working away to undermine our capitalist way of life, and human waves of medical migrants responding in caravan after caravan. Where is the army when you need it?
