I have argued for nearly fifty years that the viability of sugar rests mainly on the relationship between labour and ownership.
I am only taking the pre-slavery arguments of Dr. Eric Williams, and developing them to apply to post-slavery sugar production.
My contention, briefly stated, is that indentureship was a more exploitative form of slavery, which I, using in part, several Commission Reports on the Sugar Industry, was able to substantiate in a paper I did (and still have) for Labor Economics at UG about forty years ago.
And it will remain unprofitable, unviable, and eventually become a serious socio-political canker, unless and until labour is an integral part of ownership and management.
My argument is that sugar has always had a close affinity to slavery, and never, never morally and psychologically moved away from this mode of production.
