Elon Musk, you may have noticed, has gotten a lot of attention recently. It’s not only that he was chosen to host “Saturday Night Live” on May 8 or that there was another fatal crash under suspicious circumstances of a car made by his company, Tesla, but also a surge in his charitable spending. In just the first four months of this year, Vox.com reports, Musk has donated $150 million to philanthropic causes. That sounds like a lot of money. Vox calls it a “philanthropic spending spree.” It’s wonderful that Mr. Musk is giving away some of his wealth, but apple pie is also great and so is calling your mother on her birthday...But none of those things excuse us from our obligations to pay our fair share of taxes.
