I think you also have to see it from the standpoint of how the dynamic works. While the situation you pointed out would, without further detail, be hypocrisy, it's also a matter of what conditions both parties were already in. In the United States one drag to Californians' reputation is the fact that oftentimes they are wealthier than the people of the state they are moving to and in term disrupt life for the locals, whereas a Latin-American moving to the United States can typically be there for opportunity but without prior economic status to be considered a burden on the locals. For the very same reason Californians are disliked in the U.S.; expats are disliked here but with them furthermore not attempting to even assimilate or contribute to the city in a way that doesn't make things harder for the natives. One can't even say these people came for a better life like one immigrating to the United States would, as in many cases they have no interest in learning the local language nor actually immigrating. Of course there are holes in this but we aren't to say that more opportunity exists in Mexico that wouldn't exist in the United States.
