In the past six months, Mackenzie has donated $4.1 billion to 384 grantees identified by her and her team of advisers as serving "communities that face high levels of food insecurity, high levels of racial inequality, high local poverty rates, and low access to philanthropic funding."

When the New York Times reported on Mackenzie's charity, it described it this way

"They [donations] are like secret gifts from Santa Claus, $20 million here, $40 million there, all going to higher education schools, but not to elite universities that usually have a high profile." These donations are going to colleges and universities that many people have never heard of -- schools that educate district, minority, and low-income students."

"I was very shocked," Ruth Simmons, president of Prairie View A&M University in Texas, a historically black college, told The New York Times after learning that Mackenzie would donate $50 million to the school, It was the largest donation the school had ever received, and she even thought she had misheard it, as the caller had to repeat the amount to her and tell her it was $50 million.

Mackenzie's actions are in stark contrast to those of her ex-husband, the world's richest man.

Over the past few years, Bezos has bought luxury homes in Manhattan's Central Park South, Washington, D.C., and Beverly Hills in Los Angeles, with the Beverly Hills mansion becoming the most expensive home in Los Angeles when it sold for $175 million.

He also owns a 300,000-acre estate in Texas.

Not only does Bezos love to buy luxury homes, he is also keen to travel around the world with his new love. At the same time, he was methodically squeezing Amazon employees against their attempts to unionize.

Mackenzie is estimated to have given a total of $6 billion in 2020, and experts say she could be the largest living donor in history to give directly to charity in a single year.

The news of Mackenzie's new marriage came last month when another name was added to The Giving Pledge page.

It turned out that less than two years after her divorce, Mackenzie had fallen in love again and had remarried, to Dan Juett, a chemistry teacher at a private school in Seattle.

The two met because Mackenzie's children attended the same school.

As for Dan, his students describe him as "very engaged, energetic, enthusiastic, friendly, sociable, and very serious." It was clear that he loved what he did, loved teaching, loved science, loved working with students... He's so charming, you want to take his class."

After a lifetime of teaching and never getting involved with The rich, Dan says in his letter to The Giving Pledge: "For me to write a letter promising that I will give away the vast majority of my life's wealth is amazing. Because I never imagined that the property I owned would one day make this matter of any significance."

It was also the letter that made the normally low-key Mackenzie's new marriage known, because Dan said of their marriage, "Now, in a happy coincidence, I have married the most generous and kind person I know, and together with her I have pledged to give away my vast wealth to those in need."

At the age of 49, the world knew that her husband, who had been self-made and accompanied for 25 years, had a new love, but she not only broke up with her husband decently, but also generously gave up most of her property, and turned around and said that she wanted to donate all the money.

Now, at 51, she has found true love again - a man who is as indifferent to fame and fortune as she is.

Her excellence is higher than wealth; Her structure and heart are admirable. Such a woman, no matter who her husband is, can have a long life of happiness.

At The end of Mackenzie's The Giving Pledge letter, she writes

"Each of us is blessed with influences and lucky coincidences that we could not have anticipated or understood. As for me, in addition to the wealth of experience that life has always brought me, I have a disproportionate wealth of money to share.

The charitable path I choose will always be deliberate. It will take time, effort and care. But I won't wait. I'll keep going until the safe is empty."
