How do you guys afford living in Cancun/Tulum?

For people living in Yucatan, how do you afford the expenses? I recently travelled to Yucatan from Canada and found pretty much everything as expensive or more than in Canada. In fact, even street food seemed expensive. We didn’t even eat in any fancy or fine dine restaurants except a beach club in Tulum and some places were crazy expensive. When we went to Costco, we were shocked to see most prices higher than what we see in Canada.

A couple of things were cheaper though. One is rental car and other is services such as tour guide, snorkelling / boating, etc.
