I sometimes wonder if the friends who go abroad to serve "where the need is great" are not simply going because "their needs are great."
Would be fair on this. These JW's spend their own money so they are welcome to go where they want. At least they not like cedars who was asking for money from child abuse victims for his book and was seen holidaying in Venice.
One cannot discredit them simply because the country has good beaches or has good tourist destinations. There are good beaches in India too, and there are many young American and British JW's who have come here to preach. Mind you, it's a complete shit hole of a country and having good tourist destinations doesn't make your life automatically enjoyable.
There are many JW's who actually live and preach in dirt poor countries. In many third world countries, the growth has been attributed to these need greaters.
