A common problem faced with all new revolutionary governments is staffing their government agencies with trained people. This was experienced by the Russian Revolution in 1917 when they had to use many holdovers from the Czarist government. This has been pointed out as a problem for the Chavez revolution in Venezuela. See this and this. Now this phenomenon appears to be causing problems for real changes in Bolivia.
In many cases, due to the lack of trained professionals in the peasant and indigenous organisations, Morales was forced to rely on “invitees” from the already existing state bureaucracy to run the government.Also, see this.
Most of Morales’ first cabinet came from these sectors, causing concern among the founding organisations of the MAS, who felt they were not being treated as they should be, with quotas in the government.
...Now in government, many of these groups began to view the MAS as a vehicle to access employment in the public service, just as the middle classes did with their parties when they were in power.
