Answer: Petitioning the government is useless because it does not always result in  action.
Explanation:
Thoreau questioned the effectiveness of change inside the government, arguing that voting and petitioning was often useless.
Thoreau was a fervent critic of the American social organization and policies, particularly slavery and the Mexican-American War, as he thought they were proof of the government being an unjust institution.
He stated that protest was better than advocating for reform from within government because those in government couldn´t see the wrongs.
