Colonists on Mars would have to deal with extreme environmental conditions and therefore be forced to invest the majority of resources in science and engineering instead of politics and entrenched systems.
Also, martians would be natural space travelers. Mars has a gravity that's less than half of Earth's, so they would get off that rock much easier and they would have a wealth of natural resources through asteroid mining that they could sell to earth together with advanced technology.
After a few centuries the martians would push the technological boundary far beyond what we have now and give Earth the motivation to follow suit to ensure sovereignty.
