So difference is culture of South America and Mexico and how they alike is that South America is quite on like the Mexico in terms on their history and the Spanish is the real connection of both two and the difference of all of them is their foods, manner and basic habits that both have molds in past years
I'm guessing the answer will be offering 50 acres of free land to practically anyone would could pay for their own way there. or they can use it for farming. the large amounts of labd and increased availability of labor allowed for the growth of plantations
hope this helps!!
