Its pointless to argue about when it happened. The “when” is different for different parts of the country. southern california was inundated with illegals in the 70s. The corn belt wasn’t inundated until the 90s.
BS...No it wasn't, not even close. I likely forgot more about California than you ever knew.
The waves of illegals really started in the mid to late 80s...The big push across the borders starting in the early 90s when an endless conga-line of tens of millions came across...It's was like a Boston marathon of millions...
It was relentless all the way up to what we have today.
Nothing compares to the epic invasion we've witnessed for the past 20 years.
