Elvis facts: Not accounting for inflation, by the time Elvis dies in 1977, he was estimated to have earned over $4.5 billion. And since then, he has continued to top the Forbes list of top dead celebrity earners in multiple years. And in several years, he was the greatest single taxpayer in the US, and always insisted on paying his fair share, and having everyone who worked under him do the same..
He was also known to be exceedingly generous. One day, while driving around in Memphis, he saw an elderly lady struggling with her wheelchair, so he immediately arranged for her to get a motorized wheelchair, even going so far as to personally assist in seating her in it, and showing her how it worked. Her son remarked how nice Elvis' car was, so he gave it to the man on-the-spot, and even gave the man's son a job. He was also a staunch admirer of Martin Luther King and the civil rights movement in general, but Elvis' manager resisted arranging a meeting between the two because of concerns that people in the South at the time would disown or boycott Elvis for meeting MLK.
In the year he died, he was the largest concert draw of the year, despite only touring for less than a month. And despite being considered very simple & nonconfrontational, after one concert in the '50's, an opera singer approached Elvis backstage, and told him that he sang like a Hillbilly. Elvis, in an uncharacteristically laconic response, stated "And how many came to hear you sing tonight?"
