Except for taxes. Anybody, who will live on Earth and be above average, will need to support other living beings (humans, animals, fish, forest, grass, birds, insects) with his taxes, otherwise we will have dirty cloak with few billions of angry and hungry living beings, which can dig you out of any bunker.
At Mars, it will be hard to survive without external support for about century, but much lower taxes and self selection of educated people with high IQ can make it booming.
