I have had those road side tacos in mexico (although they costs 2.5 pesos when i was there in 2005.) They are so tiny, you really have to order 8 to 10 of them to fill you up. I dont even think eatting one would be enough to fill up the belly of a 2 year old.
I think credit will never go out of fashion. If people were not to get credit, no new businesses will come out since only the people who alreday have the capital will be able to come up with new businesses, and we all know that people who have already have made a lot of money have little incentive to create new and dynamic businesses.
