Class Clowns: How the Smartest Investors Lost Billions in EducationThe past thirty years have seen dozens of otherwise successful investors try to improve education through the application of market principles.

The past thirty years have seen dozens of otherwise successful investors try to improve education through the application of market principles. They have funneled billions of dollars into alternative schools, online education, and textbook publishing, and they have, with surprising regularity, lost their shirts. In Class Clowns, professor and investment banker Jonathan A. Knee dissects what drives investors' efforts to improve education and why they consistently fail. Knee takes readers inside four spectacular financial failures in education: Rupert Murdoch's billion-dollar effort to reshape elementary education through technology; the unhappy investors--including hedge fund titan John Paulson--who lost billions in textbook publisher Houghton Mifflin; the abandonment of Knowledge Universe, Michael Milken's twenty-year mission to revolutionize the global education industry; and a look at Chris Whittle, founder of EdisonLearning and a pioneer of large-scale transformational educational ventures, who continues to attract investment despite decades of financial and operational disappointment. Although deep belief in the curative powers of the market drove these initiatives, it was the investors' failure to appreciate market structure that doomed them. Knee asks: What makes a good education business? By contrasting rare successes, he finds a dozen broad lessons at the heart of these cautionary case studies. Class Clowns offers an important guide for public policy makers and guardrails for future investors, as well as an intelligent expos for activists and teachers frustrated with the repeated underperformance of these attempts to shake up education.Binding Type: Paperback

Works well, worth buying.
Color: Rechargeable with Storage Stand and Box - Black
Works really well. I wish the attachments were easier to get off without feeling like you are going to break them. I use a butter knife to pry it off carefully. I like having the case too, it works well if you need to travel with it.

Reliable favorite kitchen tool
Color: Blue
This wonderful tool may be the most used tool in our kitchen. The hardest thing about it is to remember you can push the button and it runs- you don't have to hold it!. The charge on the rechargable battery last a long time- about 1 recharge per month- and we use it daily. We use the mixer attachment most. It works great for protein powders, collagen, iced tea or lemonade mix. It cleans easily and is waterproof- just make sure the cover is over the charging port. We have used it to froth milk, whip eggs, and as I said we use it daily to mix beverages. I worried about the price, but it is a great value because we bought it in December 2024 and it is more powerful and has already lasted longer than two whimpy ones.

Quality
Color: Black
This is by far the best frother I've used. Battery life is great. Its UX is excellent. Feels nice in the hand and has great power. Also like the on/off button as opposed to haveing to hold a switch down. Looking forward to getting their s3 scale.
