I don't believe there was any utopian period in the past, but in US history, the Gilded Age had a lot in common with our current day (corruption, centralization of wealth and power, stemming from new technologies). And it was followed by the Progressive era and then the New Deal which were distinctly more populist in nature. Those were the eras of American history where the US got serious about anti-trust and unionization respectively.
