In business there will ALWAYS be brokers, especially if the producers are poor or illiterate (no pun intended) or when the gvt is not making initiatives to help farmers, the brokers are usually the bridge between the producers and consumers, thats where the Kenyan broker fall in, with his easy access of money (Thanks to financial institutions in Kenya), unexploited ventures and wit, they charm their way into the stores of the Tanzanian farmers and get the products for cheap through trickery and cartels.
What am trying to say is that the broker is not the devil, even if you ban the Kenyan brokers there will always be people who are ready to fill the void left by the Kenyans.. you cant tell me that the Kenyans were working alone deep in the heart of Tanzania without the help of some locals, this is not a one mans affair, there must be someone who introduces the brokers to the farmers and also contributes in setting the price, its obvious. what the government has done is simply changing the brokers, what will happen is the cash deprived Tanzanian broker will be used by the moneyed Kenyans to buy the produce for them at an agreed price, yes the Kenyans wont get as much as they used to, but eventually they will have their hand in setting the price.
No am just saying.
