No one makes that much money through work, it is through investments. Remove social security tax limits and beef up our nationalized retirement systems then tax investments to death. I don’t care if people are disincentivised from investing in businesses that don’t make any money. I know I’ll ruffle some feathers with this but I truly believe all space travel investments should be redirected to something that can make an immediate difference for those already on the planet, like healthcare or services for those effected by climate change.
