Why American intervention in Mexico was criticized by many Mexicans and international observers as being hypocritical

When we did the intervention we also set ourselves up for disaster due to putting a border on Mexico making it more attractive to come illegally thru America and we deport alot of them what's hypocritical about that is if we had not put a border and not Intervened into Mexicos business, America and Mexico would have hashed out a proper plan and have made the legal idea of moving to America the only reason to go there.
