Final answer:
An oligarchy and a dictatorship are forms of government that are usually shunned as they centralize authority among a limited group or an individual, while democracies are celebrated for distributing power among many individuals or representatives.
Step-by-step explanation:
The form of government that is generally shunned due to its tendency to concentrate power into the hands of a small, elite group or an individual with minimal or no participation or representation of the general population is an oligarchy and a dictatorship. An oligarchy is a system where power rests with a small number of people. These people could be distinguished by royalty, wealth, family ties, education, corporate, religious, political, or military control. Similarly, a dictatorship is a form of government where a single individual holds all power, often with little or no democratic process, and can rule with total authority over the state.
Dictatorships and oligarchies are often characterized by the suppression of political opposition, a lack of individual freedoms, and a disregard for the welfare of the general populace. In contrast, in a democracy, power is vested in the people and exercised through elected representatives, which is considered to be a more just and equitable form of government that tends to protect citizens' rights.
