Not gonna celebrate something Jeff Bezos did, I think I have voiced my displeasure with him enough for people to know I am not a fan. But I have no problem if others commend him. It is a significant amount of money. Donationing 7-10% of someone's net worth is significant. If a regular person did that they would definitely feel it.
The reason he is rightfully get this much flack is that he undermines effort to raise more revenue in order for society as a whole to make the necessary changes. This is something I pointed out to DWalk about the downsides to private donations. Not only is 10 billion not nearly enough, solving social and economic problems now are dependent of how altruistic the billionaire and millionaire class is. Some of the blowback from the Bernie crowd is because Bernie has this weird personal beef with Bezos. I doubt if Bill Gates made this commitment, there would be this much blowback. But If Bezos was out there acting like he is find with Amazon being tax and regualted fairly, people would be less upset. Bezos is ******* hypocrite, so I see not reason to celebrate him.
BTW, their is tons of blame to go around for the current state of affairs. However, Climate Change is not just a failure of capitalism, that is a convenient answer. A socialist economy could have us in this predicament. Not because workers have more power in a friend decisions means they will not rent week. Hell a bunch of social democracies are propped up by fossil fuel money. Unfettered capitalism produces disasterous results, but so does any economic system that is not well managed and organized.
All things considered, Climate Change is mainly a failure of government. To identify a problem, probably regulate it, and manage the economy in order to align incentives so a problem gets solved. Governments are economic actors, and they have been completely been asleep at the wheel. A market economy could have been organized to fight climate change. And of course firms have used their money and power to bend governments to their will in America and some other nations. However, look all over the world even in countries with different laws on lobbying and relationships between firms and government, and you will see similar inaction. So as always, no matter the economic system, good governance matters.
