On my first trip, driving in Mexico with Mex-US sweetie, I got the mini-history of PRI - kept in mind as I saw first-hand the conditions and the miniscule rich + vast majority. "Institutional revolution" indeed - like most pol-babble it was the precise opposite: read reactionary for "conservative" (even Mexico at least skipped.. the absurdity of calling that 'compassionate' - but we'll swallow anything).
I do so hope that the mordita culture is dying out at a decent rate; it was is? too widespread an institution ever to kill in just a few years. Ergo: you never could get 'justice' - a fact I witnessed when involved in a minor traffic mishap (P. drove it into a bank to avoid a driver). While we were at some estaci\ufffdn.. an obv. dirt-poor farmer truck owner was paying his little sop, to get his truck out of hock. Poor bastard; we dared not 'interfere' even to slip him a hundred (not chickenfeed for us either - but lots for him). Then there was the sleeping guard in Barrio de Navidad - with a machine gun on lap..
Anyway, there seems never to have been an intent of the PRI to export (!) its system of subjugation: whereas with the Nazis, that was paramount.
Viva Nuevo Mexico, then..! (no not ours)
