I would also assume that Denzel has more money than Gary. So Denzel would have more to donate compared to him.
Are you saying Denzel does donate more to charity than Sinise?
If you have $1,000, and I have $2,000, would you be more generous giving a $200 donation than I would be giving the same amount?
Do you calculate the amount one must give to charity similar to tithing? If both Denzel and Gary gave 10% of their income to charity, would that make them equally generous if Denzel's net worth is $140M and Gary's is $50M?
What about the charities they choose. If Gary supports mostly wounded vet charities, but Denzel supports a wide variety of charities for the youth, does one seem like a more worthy cause than the other?
Is it more charitable to simply give away one's wealth, or is it a better choice to invest part of if to provide jobs and benefits for many years to come?
The money someone earns and accumulates is theirs. They are free to spend it as they wish. If one person gives more money than another, but the other gives more of his time, is it really a good metric to simply compare checks written to worthy causes?
