You don't know anything about his inheritance, other than he met with the requirement to give a portion to Mormonism, you don't know how much it was, or it's disposition, or the split among the siblings, nothing. We don't we even know when he received whatever he received, his dad died in 1995, but his mother died much later.
He didnt give his ingeritance away to charity
It was used to curry favor when he wanted to run for office...
he gave it to BYU to build a business building named for his father George...
The Mormons are backing him in spades...
It was an investment for himself...
Willard never does anything just for the heck of it...
Theres always some strings attatched...
and some type of record kept about his “goodness”
