: Why does wealth turn people off? Wealth is a sign of success, so what's wrong with it?
Wealth is a sign that you have successfully ripped other people off, or ripped off the planet's resources. You can't get rich without paying workers less than the value of what they're producing, or without charging customers more than what the product cost you.
Your wealth makes other people's poverty.
: So what? Charity is good whether or not you go bankrupt givign to it.
Charity is not good full stop. Even when given with the best of intentions it does nothing to alter the power imbalance that led to the recipient 'needing' charity, and you being able to give it. But charity for advertising purposes is positively evil and dangerous, because its purpose is to manipulate people into thinking that the company cares and is therefore ok, diverting attention from the fact that companies like McDonald's are making their profits from exploiting people and damaging the environment. Its much more effective than normal advertising, people realise that is designed to sell them the product, but they don't always realise that 'charity' by corporations is also designed to sell them the products, so they view it more positively.
