Do you think by "remnants of colonialism" the OP meant "capitalism"? It's plain to me that he did not. I read it as him meaning an extensive bureaucracy designed to control the subject population is still in place and causing the price of the good to rise while the actual people who produce and innovate the product are left out of sharing in the windfall.
You say colonialism opened up Kenya to the global market. But nearly every country in the world, the colonized and the uncolonized, is now part of the global market, so it is not true that Kenya would not be part of the global market today without it.
The global market we have today is the result of an ordering of things that is a remnant of colonialism -- I think that is what fsckboy is referring to. It could have happened another way; but the particular one we have happened this way.
The argument goes -- and I think there is a lot to this argument -- that using "remnants of colonialism" to refer only to, for example, an extensive bureaucracy that excludes people who produce much of its proceeds is misleading, because other extensive institutions that are also remnants of colonialism are an important part of commerce, law and order, and public welfare all over the world.
Why do you think there's a lot to this argument? Genuinely curious.
Who said police, courts, etc. are not remnants of colonialism? Also, what is the relevance of that to this discussion about coffee selling and the problems in the Kenyan coffee market?
