In a democracy, citizens are guaranteed four basic and inalienable rights; freedom of speech, freedom of religion, the right to assemble, and equal representation before the law. Citizens get to enjoy expressing their opinions openly, going anywhere and doing anything they please, and making (and keeping) their own wealth. Democracy protects every person's individual freedoms.
In autocracies, these rights are not guaranteed. In countries such as North Korea, people are censored on a disturbing scale. The government controls all domestic TV, radio, and newspapers, and international news reporters are limited or even barred from covering or being at certain events.
Democracy allows for anyone to report on the news, allowing for many different accounts and perspectives on any given event.
People gathering for protests has also been a right enjoyed by the people in a democracy. Despite government intervention where quarantines have been put into place for Covid, people in America still gather to protest the blatant disregard of human rights as shown in the George Floyd case; and in a democracy, they are protected by the law. Their right to protest is still supported, and they are even given recommendations on how to protest safely during the pandemic.
In a democracy, one keeps what one earns. This is a freedom that people under a communist government, for example, can't say they enjoy. Because wealth is distributed evenly, and resources and businesses are owned by the government, people can't even produce their own goods; the state takes it and distributes it based on their own criteria.
Democracy would never allow for people to be taken advantage of in this way. If, for example, a person wants to grow their own food, then they have the freedom to do that and not have it taken away and given to someone else.
Democracy advocates for, ensures, and protects personal freedoms for every citizen. For this reason, it is the best form of government on earth.
