My 25 year old daughter is the Executive Director of the Sister Communities of San Ramon, Nicaragua. This organization got involved in Nicaragua over 20 years ago just after the Sandinistas prevailed in the Contra War. They developed and support an eco-tourism lodge and coffee farm called the Finca Esperanza Verde. They help build schools, rural health clinics and more. The local citizens decide what they need, are invested in building the facilities, and run and manage everything. All wages are generally equal to at least 1.5 times the prevailing wage structure.
They have developed and posted a number of videos on YouTube documenting their work. Check it out. Pretty powerful way of American citizens helping others to help themselves. I have been there and witnessed first-hand the quality and lasting effects of the efforts of this particular non-governmental organization. It’s inspiring.
