In the United States, citizens have quite a few options if they do not like the laws implemented by the government. The U.S. is a republic, meaning that power belongs not to a king or queen or dictator but to the citizens themselves. The most prominent way for citizens to use that power is by voting. They can vote for government officials (like senators, congressmen, or the president) who they think would represent their interests, just as they can vote AGAINST officials they dislike. There's also another kind of voting, called a referendum, in which the government asks the people to decide on a very specific issue (like whether a local highway should have a toll, for instance, or if the sales tax should be raised to help fund schools).
Citizens also have a constitutional right to "petition the government." This means that they are allowed to protest against laws and politicians (as long as they do so peacefully) and that they can send lobbyists to their government to ask politicians to change certain laws.
