Why don't even strong democratic theories; Nor do any political system works in this small nation

...; ideally, a democracy functions on the basis of the formal exercise of political and civic rights (freedom of expression, of association, etc.), the full political participation of people (i.e. every citizen should have a say in matters that affect his/her life), an accountable and transparent government and well-functioning electoral institutions, etc. In practice, however, these democratic ideals are never fully observed. Contrasting the practice of democracy with its ideal, Drèze and Sen (2002) observe that the actual practice of democratic ideals in a given society critically depends on a large array of factors. They cite the following: first, the practice of democracy depends on the extent of political participation, like election turnouts, the number of political parties, and the number of people who present themselves in elections. Among other factors that disrupt democratic institutions are inefficiency, corruption, incompetence of the bureaucracy and lack of motivation.  Further, when people are not well-informed about different political parties and their programmes or when they do not have the educational level to understand their programmes or the policy issues that concern them, their vote may not reflect their best interests. The situation gets worst in developing countries where people's choices and Vote/s are influenced by various factors & institutions that affect thier day to day lives. Chronoic poverty and low literacy rate has always provided fertile ground for Vote Bank Politics; neverthless, " Selling of Votes" has been a good practice among people for livelihood opportunities.

Nepal could be a best example to study; the country has seen the Monarchy, the Ranas (Dictators), Pancha’s (the Panchyat System), Political Leaders (Multi Party Democracy), Maoists (Revolutionaries transforming into political party) and now Mr. President, but all so far nothing have worked out. The nation is struggling hard not to be tagged as state of failure. Whilst, the next agenda is federalism (pinned up with a new culture in nepali politics ie. "Political Polarization" along with gradually/systematically being democratically-constructed particularly negative values like racism.) The question is why don't even strong democratic theories, nor do any political system  works in this small nation once which was viewed as zone of peace.
