They are not a net benefit tax-wise, and anyone who has lived in these areas can tell you. Public schools, which are utterly inundated and massively overcrowded in these places (as well as in other non-border towns that have large undocumented populations such as Springdale, Arkansas), are primarily funded by property taxes. And having lived in neighborhoods that were predominantly populated by undocumented migrants, they tend to rent apartments/houses and pack in 2/3 to a bedroom, which means that there is no net increase in property taxes. And if you think that sales taxes paid by a frugal new immigrant remotely covers the roughly $15K a year it costs to educate a pupil in a public school, you are absolutely not doing the math honestly. The amount of willful blindness on this topic is amazing.
