Historically, what has been the policy of most countries regarding indian languages in latin america?

In general, the native Indian languages in Latin America were able to survive. This was because the colonial governments were not forbidding the native languages and were not punishing the people for using them. Instead, the politics was, that the language of the colonists is a must-known language for everyday communication between the different people, but they can use their own languages in the communication between themselves and at home. This is why the countries in Latin America nowadays have multiple official languages, most of which are native Indian languages.

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.
