Has a single billionaire spoken out against Schumer-Rubio?

According to Forbes, there are a little over 400 billionaires in the U.S. Many (such as the Koch Brothers, Mark Zuckerberg, Bill Gates, Michael Bloomberg, Rupert Murdoch, and George Soros) are actively using their money, influence, and power to promote more immigration. (And this is not to mention foreign billionaires, such as Carlos Slim, financial savior of the New York Times, who profits exorbitantly from phone calls between Mexican immigrants in America and their friends and family in his country.)

Here's a question -- in the latest round of controversy over immigration, has a single billionaire spoken up publicly against expanding immigration?

I'm aware of a tech billionaire who quietly gave some moderate support to immigration restriction a half dozen years ago, but I'm drawing blanks on any since 2010. Surely, here in the land of the free and the home of the brave, there must be one lone billionaire who felt able to speak out against his class's self-interest. Right?

Were constantly reading in the mainstream media about how Michigan eye doctor John Tanton is this malign supervillain personally standing athwart immigration reform, shouting "Stop," but, come on ... an eye doctor in Michigan? That's it? If one billionaire spent as much on immigration restriction as several billionaires have spent on their favorite college football teams' weight rooms, we might have something not too far off from a level playing field in the debate. 

You might almost suspect that the billionaires are waging class war on the citizens of America.

As Swift would say if he were alive today, "When a true patriot appears, you can know him by this sign: that all the scoundrels are in a confederacy against him."
