The United States of America has been a democracy for more than 200 years. Issues that were important in its early years remain so today: big government versus small government, individual rights versus group rights, free markets versus controlled trade, and connection with the world versus focusing on internal affairs. The U.S. tries to be a fair and just society, and much of the time it succeeds. Through compromise and change, the country has grown, prospered, and made progress toward its ideals.
美國成為民主國家已經(jīng)有200多年。在早些年的一些重要問題如今一直存在：大政府對小政府，個人權(quán)利對集體權(quán)利，自由市場對受控制貿(mào)易，以及聯(lián)系世界對集中內(nèi)部事務(wù)。美國努力嘗試成為公平正義的社會，它的成功需要很多的時間。通過妥協(xié)和改變，這個國家已經(jīng)成長，繁榮，以及觀念上取得很大的進(jìn)步。
