Well, for starters it would involve ratifying and complying with the San Andrés Accords that the government signed with the EZLN but hasn’t followed through to date. Giving indigenous peoples permanent/proportional political representation and congress seats both in their respective regions and in the federal level. Giving them proper self-determination, returning them their ancestral lands and respecting whether they want industrial resource exploitation in their communities or not. Teaching indigenous languages in school as second languages, maybe according to the region. Affirmative action to repair the poverty inherited from colonial slavery. And so on. I think the EZLN website is a lot more eloquent on this topic.
