Back in the mid 1900's Mexico was proud to have more world boxing champions in the small categories, than any other Country. Boxing was perhaps one of the few opportunities where a typical low income Mexican(75% of the population)could have success in life. Kids started boxing in their ghettos, a few of them made it to the Pro's and an even fewer amount got to be famous and earn good money from it. Those that got to the top soon found out that suddenly they had a great amount of people that surrounded them and helped them spend their money. But immersed in their new life styles they could never leave their origins and find a better future for them.
