The rest of the place is a mishmash of semi-systems, ancient traditions with no standing in law, as well as non enforcement.
Mexico encumbers it all with land tenancy laws that hurt the poor and help the rich ~ that was part of the Revolucion's land reform ~ it kinda' backfired so you end up with more concentration of ownership than before the Revolucion. Part of that, though, is their need to compete in agriculture with the US, else cheap American crops would swamp their country.
I keep my eye on this just in case any real news pops up but ever since the Commies were demonstrated to have no use for the poor either, you don't hear their Socialist brethren hyping any sort of land reform ~ or enforcement of titles.
Quite true of the Commies; ask any Russian. For the Leftists, the “poor” are to be used for their nefarious ends. They’re seen as a tool.
