“ THANK YOU, AISEA MATIU...Subsistence economy in Tonga is a barrier to organizing an effective trade agreement in the free market. So called farmers, and fishermen, are not doing it for "commercial" purposes, or for economics purposes.
But rather a "convenience" subsistence practice:
We grow our crops, and go fishing, when we feel like it, and only to avoid starvation. Commercial trade is an after thought. Additionally, supplying the market is a product of large-scale farming and fishing expeditions to take advantage of "economy of scales." ”
