Totalitarianism includes such political systems as dictatorship, aristocracy, monarchy, one-party rule, communism, etc. To show my fairness and neutrality, I have also posted a topic entitled "Advantages and Disadvantages of Democracy". Netizens are welcome to analyse and discuss the advantages and disadvantages of both opposing political systems.
Totalitarianism can be good if it's used once by one leader. It can be used to boost the key areas of economy and bureaucracy. Getting rid of corruption and putting a check on major corporations, but allowing international trade. Import and Export are allowed but exporting is more of importance. The advantages of living under totalitarianism is that you are safe, free healthcare and broad education for everyone. You already know the disadvantages. If you are a bad leader and impose stupid sanctions on your people it's a bad place to live. Especially communist countries face high % of corruption.
