Long before the ‘60s, I suspect.
We’ve had a Deep State since the early 1910s...
When the U.S. Congress passed—and President Lyndon B. Johnson signed into law—the Immigration and Naturalization Act of 1965, the move was largely seen as symbolic.
“The bill will not flood our cities with immigrants,” lead supporter Sen. Edward “Ted” Kennedy (D-Mass.) told the Senate during debate. “It will not upset the ethnic mix of our society. It will not relax the standards of admission. It will not cause American workers to lose their jobs.”
That sentiment was echoed by Johnson, who, upon signing the act on October 3, 1965, said the bill would not be revolutionary: “It does not affect the lives of millions … It will not reshape the structure of our daily lives or add importantly to either our wealth or our power.”
But the act—also known as the Hart-Celler Act after its sponsors, Sen. Philip Hart (D-Mich.) and Rep. Emanuel Celler (D-N.Y.)—put an end to long-standing national-origin quotas that favored those from northern and western Europe and led to a significant immigration demographic shift in America. Since the act was passed, according to the Pew Research Center, immigrants living in America have more than quadrupled, now accounting for nearly 14 percent of the population.
