GDP/CapitaGDP/capita is not a good measure of how people live in some countires.
I live in the Philippines (113 on the list) in the same way as the average Filipino lives. I have lived in Moroc, 119 on the list, the same way as the average Moroccan. I have spent time in Cuba, 112 on the list. These countries have very similar standard of living similar to Nicaragua.
People in the Philippines are living just fine because they do not need a high GDP per capita. They build their own home out of local materials without need for building permits or standards. I built one for about $6,000 with solar panels. Solar panels were good and inexpensive as they come from China not so far away. Water is dirt cheap. My water bill is about $5 a month. Food is 1/3 cost compared to Canada because it is mostly locally produced with inexpensive labour. You pick up fresh fish at the market every day on your way home - $1,80/lb. Taxes are low. Fibre internet is less than half the cost in Canada. Hair cut is $1.50. Like most people we drive a 105 cc Honda with a fuel bill of about $3 a week. Most people drive small motor bikes. Cars are not needed. Homes do not require heating. Fans only required for cooling. Everything is compact so no extensive travel distances required. Bus rides are 1/3 cost of bus rides in Canada. Local trike taxi rides are about 50 cents. Restuarant meals are 1/3 the cost of meals in Canada. I could go on and on. Very low unemployment because a very large portion of the population work in the cash economy. 25% of the population is involved in agriculture that is not taxed.
Nicaragua is a tropical country very much like the Philippines. GDP/capita is a poor yard stick to compare other countries to Western standards.
Calibre Mining is making a considerable contribution to improving the well being of Nicaraguans. Relative to the size of the Nicaraguan economy Calibre's impact is significant.
