You would do the same as Branch, not everyone would. If you have money convictions, stand by them, don't try to explain them away by saying "everybody would." Because everybody wouldn't.
Here's the difference in your above example. If a family is making 20K a year, then 75K will be a tremendous increase in it's quality of living. That extra 50K will provide things not available to a family trying to live on 20K.
If a player is offered 6 mil a year (or 5.5 or whatever Branch was offered) and insists on getting 6.5 mil a year, his quality of life will not be affected at all. Going from 6 mil a year to 6.5 mil a year is not the same as going from 20K a year to 75K a year.
An extra 50K to the 20K family provides housing, education, security, and medical assistance. The extra .5 mil above and beyond 5 or 6 million provides nothing extra.
When a player wants 7 mil instead of 6 mil, that is not about taking care of his family. It is about treating money as a source of respect and self esteem. (I am worth that much. They disrespect me by offering less.) Nothing wrong with that, everyone is entitled to thier values and priorities. But don't confuse refusing to honor a contract in order to get an extra mil or so as making a difference in the player's life. Not like a family going from 20K to 75K.
(Comparing Branch to a family making 20K was a bit ludicrous anyway.)
