I believe that CCM are certain to be in the power for many years in Tanzania, and I can't expect to see a great deal of change in the country except in capital, Dar es Salaam. The country is riffled with corruption- the policy makers and regulators will only act for something that will benefit them personally.
Crooked businesses have huge influence in Tanzanian politics, some hold ranks within the main party, and few are expected to hold the ministerial positions in next cabinet. Although, there are relevant labour laws, trade and competition policies in place, as in the past these laws and policies will be used as a tools to benefit to those charged with implementing these policies, and gain competitive advantage for businesses supported by those in the ranks. Time and again, I have witnessed the basic rights of poor labourers being inhibited.
I guess, strong anti-corruption bureau (not under direct control of the politicians) will play a vital role in development of Tanzania.
