Sorry, meant no offense and may have misinterpreted the data. Perhaps collapse is too strong a word to describe the situation.
"More than half of the population is below the national poverty line, and 23% of the population lives in extreme poverty. Poverty among indigenous groups, which make up more than 40% of the population, averages 79%, with 39.8% of the indigenous population living in extreme poverty. Nearly one-half of Guatemala's children under age five are chronically malnourished, one of the highest malnutrition rates in the world.Guatemala is facing growing fiscal pressures exacerbated by multiple corruption scandals in 2015 that led to the resignation of the president, vice president, and numerous high-level economic officials."
There is a large underground economy and the “poverty” of “natives” is normal for their way of life which they do not want to leave.
