It’s Friday, so time for feedback. Lots of reaction to my suggestion that Jeff Bezos should sign the “Giving Pledge.” Among the responses:

“Wanting to take you to task a little for the criticisms of Jeff’s philanthropy. He has much life yet to live and who knows what he will do with his wealth…To MacKenzie Bezos I say thank you and bravo.” — DW

“Is it worthwhile considering that the best charity Jeff could do is what he’s doing, i.e. funding space infrastructure which is likely going to cost a large chunk of what he has left/will make. He’s effectively helping humanity pave the way to space and new (better??) ways of solving overpopulation, pollution and cracking a potential meteor problem—amongst other things.” — MS

“Perhaps during his lifetime, Jeff can do more with his money and power to benefit mankind than he could accomplish by putting billions of dollars into the hands of charities. He is young and active and can make his own decisions.” — VC

And then there was KI, who simply responded: “Please delete all my subscriptions to your newsletters.”

Okay, I take the point. Or rather three points. 1) It is his money. 2) Much charity is wasted. And 3) For-profit investment can have a powerful positive impact on society. All true. But the Gates Foundation still stands as a worthy example of the power of philanthropy. And in an era when a rising chorus on the left is arguing ultra-wealth should be taxed away, more examples like Gates would make a stronger counter argument. After all, who will argue the federal government would make better use of those billions than the Gates Foundation?

I’ll be in London on Monday for the Fortune Most Powerful Women International Summit. Among the prominent women attending: Manolo Blahnik CEO Kristina Blahnik, Booking.com CEO Gillian Tans, and Softbank Vision Fund Venture Partner Kirthiga Reddy. I’ll be interviewing iTV CEO Carolyn McCall.

In its first earnings report as a public company, Uber posted losses of $1 billion on revenue of $3.1 billion for the first quarter of 2019.

History Repeated

Remember the Greek Debt Crisis? Of course you do. A repeat of that sort of mess is emerging in Italy, where the country's de facto populist leader Matteo Salvini is asserting Italy’s right to spend freely even though, like any eurozone member, it doesn’t have the right to print money to pay its debts.

Narendra and Nirmala

Newly re-elected India Prime Minister Narendra Modi made a surprise pick for a prominent cabinet post. Nirmala Sitharaman was appointed finance minister; she'll be the first woman to hold the job in five decades and will inherit an economy facing weak domestic consumption and waning global demand amid the U.S.-China trade war.

Merkel's Message 

It's graduation season, and while German Chancellor Angela Merkel didn't vow to pay off student loans in her commencement speech at Harvard on Thursday, she did cause a stir by taking not-so-subtle aim at Trump in urging the Class of 2019 to "tear down walls of ignorance and narrow-mindedness."

A Win for Dad

JP Morgan Chase agreed to pay $5 million to settle a discrimination claim filed by a male employee who argued the bank's parental leave policy was biased against dads. He was denied the bank's 16-week parental leave, and offered two weeks of leave instead, on the grounds he was not a primary caregiver. The settlement, Bloomberg reports, is "the most high-profile warning to companies with policies that are gender-neutral on paper but not in practice." Bloomberg
