Mexico has property taxes already. They are called "Predial" for houses/land/etc... and "Tenencia" for vehicles. They are to be paid annually and don't come cheap as you put it. It would be terrible to increase their prices. Besides, almost all mortgages in Mexico are done with "Fovissste" and "Infonavit," which are the government's houses of credit. The money lent to you is in fact your own earnings taken away from a special tax that is 5%. Plus, you have to pay the interest. If the interest is increased and people don't pay, they are thrown into jail and have their belongings sold. Then, banks repossess the now-vacant properties.
Cokes and cat food have a tax included in their prices. It is called "IVA." And so does everything else such as gas, and water. Taxing more for these items is blatantly *****ic.
Mexican public universities are "free." However, the usual unofficial "institutional fee" costs vastly. So, education does come at a great price.The downside of being "free" is that you compete against 5,000 people for 1 spot. For this reason, no one leaves his home institution. In fact, a transfer is merely impossible.
Mexico has no system of immigration in place. No one really cares, unless you are the 0.1% of what's wrong with the country.
No one in Mexico pays $30 usd on taxis. They use public transportation to get to the clinics=$0.50 usd.
