Can a Multicultural country be controlled by democracy and is autocracy a better answer?

Look at China. Soon to be the worlds superpower, weathiest nation, most influential etc etc & not a mewling democrat in sight. Democracy, like communism, is a beautiful ideal but a impracticable. With Multi-culturalism comes disunity as each group seeks to benefit & preserve 'their own'.....in a globalised world the only clear path for stable & civilised government is autocracy. The EU knows that their is no way they can satisfy 500,000 citizens & if the EU were truely democratic it would stagnate under the weight of contested legistlations, legal wrangelings, interpretations of law & most of all trying to satisfy 27 differing cultures with 27 different opinions/world views etc etc....... Autocracy is the only way to move.
