As a foreigner living in Huatulco, will I have access to public healthcare? What is it like?

"Currently the Mexican heath care system is being revised by the new President MACRO. They are doing away with one of the options that is often abused by expats which is meant to be used by the poorest of poor Mexicans. This option I would never recommend regardless as the doctors in many cases have not finished their education and you are taking a huge risk. Then there is another option which employers are required to contribute a portion to your coverage. But, as expats the most popular option is to purchase PRIVATE HEALTH INSURANCE. Pre-existing conditions are usually not covered. Public hospitals are not up to the US standards in the majority of cases, which is why most expats choose to use PRIVATE hospitals with PRIVATE insurance coverage," said another expat in Huatulco, Mexico.
