Seeking to ease one’s conscience by means of spending excess money is hyper-individualistic and conforms with a self-interested worldview.
The perverse thing is how neoliberalism has left people with the idea that they can meaningfully impact the world through deciding where they spend the pittance left them after their bosses and government warmongers have taken their cut.
If you give a shit about the environment stop believing the propaganda that market forces will be swayed by your hobby of guilt spending. It will be the hard work of organizing people and uprooting the financial interest who direct national and global policy.
Wake me up when my pay has caught up to the last few decades of inflation.
