I find the notion that people illegally entering the country are going to be spending tens of thousands of dollars on their daughter's quincinera is highly improbable
I don’t know about the south, but the Hispanics in the north are not big spenders in dentistry. The northern states are more blue states and big on social services - specially in medicaid & CHIP enrollment.
9 out of the top 10 medicaid states (by coverage) are in the north, which means the Hispanic communities in the north fair better than the southern Hispanics in utilizing Medicaid for their dental services. In my state, medicaid covers ortho for anyone under 21, and pretty much everything else. So there is definitely geographical consumer behavior by Hispanic communities within the US. The southerners are probably more cash paying for their healthcare services, and doesn’t mean the parents are cash strapped or don’t have the means, but it’s the same reason why some states have more lay-aways or payment plans than others - and it’s just how business is done regionally.
There is also far less illegal immigration in the north compared to the south. There is also less mobility in the north, most Hispanics don’t move around like the southerners. The north is more difficult place to live due to cold winters and less diversity. I’m generalizing here through personal observation, but Hispanics like to live close to other Hispanics. My state is 85% white, so Hispanics resides in the urban areas of the state. Compared to Texas or
California - they are scattered across the state, but then again Texas was part of Mexico centuries ago. So the whole illegal immigration is political, which is used as a tool to energize voters. Certain US senator criticized illegal immigration from Mexico, next thing you know - he is vacationing in Mexico with his family.
Illegal Hispanics typically don’t have social security number and will not be seen by most dental offices without an ID. I was an immigrant first couple
of decades of my life, although legal, my parents or
most parents would not dole out thousands of dollars to cover expensive elective treatments. Many wait as an adult to worry about those non-essential decisions later in life. The priority for any immigrant has always been security, food and shelter, teeth will never rank higher than those top essentials. It’s super rare to see wealthy illegal immigrant.
