Rex Sinquefield is a self-made billionaire in St. Louis. He grew up poor, unlike most of today’s billionaires. He lived in an orphanage. Having pulled himself up from rags to riches, he thinks that everyone else should do the same. He has a passion for protecting his wealth, cutting public services, and reducing taxes. He has no compassion for those less fortunate than himself. None.

Here is what you need to know about him.

“Sinquefield is doing to Missouri what the Koch Brothers are doing to the entire country. For the Koch Brothers and Sinquefield, a lot of the action these days is not at the national but at the state level.

“By examining what Sinquefield is up to in Missouri, you get a sobering glimpse of how the wealthiest conservatives are conducting a low-profile campaign to destroy civil society.

“Sinquefield told The Wall Street Journal in 2012 that his two main interests are “rolling back taxes” and “rescuing education from teachers’ unions.”

“His anti-tax, anti-labor, and anti-public education views are common fare on the right. But what sets Sinquefield apart is the systematic way he has used his millions to try to push his private agenda down the throats of the citizens of Missouri.

“Our review of filings with the Missouri Ethics Commission shows that Sinquefield and his wife spent more than $28 million in disclosed donations in state elections since 2007, plus nearly $2 million more in disclosed donations in federal elections since 2006, for a total of at least $30 million.

“Sinquefield is, in fact, the biggest spender in Missouri politics.

“In 2013, Sinquefield spent more than $3.8 million on disclosed election-related spending, and that was a year without presidential or congressional elections. He gave nearly $1.8 million to Grow Missouri, $850,000 to the anti-union teachgreat.org, and another $750,000 to prop up the Missouri Club for Growth PAC.

“However, these amounts do not include whatever total he spent last year underwriting the Show-Me Institute, which he founded and which has reinforced some of the claims of his favorite political action committees. The total amount he spent on his lobbying arm, Pelopidas, in pushing his agenda last year will never be fully disclosed, as only limited information is available about direct lobbying expenditures. Similarly, the total amount he spent on the PR firm Slay & Associates, which works closely with him, also will not ever be disclosed. These are just a few of the tentacles of his operation to change Missouri laws and public opinion…”

Sinquefeld has lobbied to eliminate limits on campaign contributions and to eliminate state income taxes and property taxes. He has a special passion for eliminating teacher tenure, gutting teachers’ unions, and promoting vouchers.

“Nowhere are Sinquefield’s destructive intentions clearer than in his campaign against public education.

“I hope I don’t offend anyone,” Sinquefield said at a 2012 lecture caught on tape. “There was a published column by a man named Ralph Voss who was a former judge in Missouri,” Sinquefield continued, in response to a question about ending teacher tenure. “[Voss] said, ‘A long time ago, decades ago, the Ku Klux Klan got together and said how can we really hurt the African American children permanently? How can we ruin their lives? And what they designed was the public school system.’ ”

“Sinquefield’s historically inaccurate and inflammatory comments created a backlash from teachers, public school advocates, and African American leaders, who called it “a slap in the face of every educator who has worked tirelessly in a public school to improve the lives of Missouri’s children.”

“The statement would be easy to write off as buffoonery if it didn’t come from Sinquefield, who has poured millions from his personal fortune into efforts to privatize education in the state through voucher programs and attacks on teacher tenure.”

The jewel in his crown is the Show-Me Institute, a libertarian “think tank” that he funds to supply advocacy and research for his ideas.

Got the idea? A billionaire who hates the public sector.
