As you probably know, there have been many layoffs across the tech sector in recent months. At the same time, unemployment is close to a 50-year low, at 3.2%. Employers are raising wages to attract employees for low-wage jobs. Why is the tech sector in trouble? I’m no financial or corporate expert, so I can’t explain what is going on.

But something caught my eye as I read a story about Salesforce, which was both very successful and yet laying off 10% of its employees.

The company has been dogged by five activist investors in recent months, and is being pressured to cut costs, but the layoffs continue in spite of a stellar quarter. In fact, Benioff bragged to Swisher in bombastic fashion: “We had a great quarter. Yeah, it’s probably I think, it’s probably the best quarter of a software company ever.”

I clicked the link to see who those five activist investors who were demanding more cost cutting, no matter how it hurt morale at the company.

The first was Elliott Management. It rang a bell, but at first I didn’t remember why. More googling and soon I see the name Paul Singer.

Singer is a billionaire. Singer is a big supporter of charter schools. Singer is a rightwing Republican. Singer loves Eva Moskowitz’s Success Academy charter chain; in addition to giving SA millions, he served on its board.

An article in Mother Jones a decade ago called Singer a “vulture capitalist” and a “fundraising terrorist.”

A few years back, the U.K. Independent said that Singer had destroyed Peru’s economy and was threatening Argentina’s. Again, “vulture capitalist.”

Singer has been called a “doomsday investor.” When he takes over, he sucks out the lifeblood.

This guide to “vulture funds” was published only a month ago.

I have been trying to understand the connection between vulture investing and the aggressive charters that suck the lifeblood out of their host, the public school system.

What do you think?
