Most of the older people in Mexico still have to work. It is rare to find someone that actually had a retirement plan. A few people that worked for the government such as teachers or those who worked for the electricity company do have a pension. Only the rich do not have to worry.
The older generation also have very strong roots in Catholicism. Trying to reach them might seem hard, but with God all things are possible. Here are some pictures of them:
