Limited government is when the government is limited to do certain things, unlike unlimited government is when the government has unlimited power. With limited government, the government has limited power, so everyone is free. For example in the U.S, there is the constitution, separation of power, and rule of law, that keeps the government limited. No one is under pressure or under control of another person. But with limited Government the government has the power to do anything, and they can pretty much control the people with all that power, for example in North Korea, if you live there, you can’t get out, and Kim Jon Un is another example of unlimited government. But anywhere and everywhere you go, there's always going to be government.
This is what most people expect from a good citizen. A good citizen follows the laws made by the government, and he or she pays taxes on a regular basis to prevent going to jail or to face other consequences. A good citizen has freedom, and they have rights to do the things they want. Citizens are free to vote, and they have freedom of speech. A good citizen is always informed about the new, and how society is changing or what changes are being made. Those were just some of the examples of what a proper citizen is like.
