If there is a large enough population of people who are every bit as interested in the ruling of the nation as those in power, then a democracy is possible.
Even if the education levels are lower, the fact that the public is paying attention, having opinions, considering options, means the government is accountable.
The public will debate, question and require answers, forcing those in power to respond.
For example, Parliament wanted to pass a law to make cabinet documents unavailable for fifty years. The public stepped up and objected. That plan was shelved.
Hence in such a nation, democracy can work.
