Many of the criminals are not even Mexicans, they are either those that made it to Mexico from central and South America or recently deported South Americans claiming to be Mexicans so that they can try to reenter the USA, the Salvadoreños and Colombians are more agresive and more ruthless and then you have the ms13 guys, so yes there is definitlly change in the level of crime, not just in Mexico but all over the world.
Many years ago some university made a study with rats and they discovered that small population with suficient food there was peace, as soon as there was over crowding of the rat population the fighhts started to increase, so get persons that do not have a job, or enough to eat and you start to have more crime, specially in individuals that do not have anchors, as in immediate family, and of course you will always have the local punks, in some comunities latelly the inhabitants have beaten and linched or burt to death individuals caught stealing.
Slowly the world will decend into anarchy.
