> nor operating a McDonalds

That was a quote of the parent.

Until last year (when he was 95), he was operating the world's largest holding company by assets and revenue.

It was also the first non-tech company to reach $1T market cap.

And, its class A stock was by far the most expensive stock in the world at $740,000 per share, more than 100x more expensive than any other US stock.

So, yeah, I think he'd be qualified to operate maybe even two McDonalds. Maybe he could even be driven to them.(Coincidentally, he is a HUGE McDonalds and Coke fan and has eaten there almost every morning for over 50 years.)

Disrespecting older people seems to be a hobby as old as Father Time.
