This source, an excerpt from a video transcript by Richard J. Murphy, argues that tariffs disproportionately harm those with lower incomes rather than benefiting the nation as a whole. The central reasoning is that tariffs, being taxes on imported goods, increase consumer prices, and those with less disposable income spend a larger percentage of their earnings on such goods. Consequently, the author contends that tariffs function as a regressive tax, easing the burden on the wealthy who spend less on consumption relative to their income, and ultimately serving the interests of the rich rather than liberating the wider population from international competition or reducing overall tax burdens.
