There are far bigger reasons to doubt it, so the "liberal media" issue is moot. Not that "liberal media" isn't a fine reason, but Jeff Bezos is literally the owner of the Washington Post. He also runs Amazon, shipping lots of Chinese goods. His bias is obvious.

This isn't even a political conflict along the liberal/non-liberal axis though, so Forbes doesn't change a thing. I'm sure you've heard of the uniparty, demipublicans, republicrats, and so on. The leaders of multinational corporations have a globalist mindset. Aside from desiring regulatory capture to suppress competition, they also have a libertarian mindset. Very few media sources and very few politicians break from either mindset by much, except some hot air from some politicians. Politicians don't last long if they anger the large multinational corporations.

There is almost nobody with interests aligned with the American worker. Of the few who are, many would admit to loving the tariffs only if somebody like Bernie Sanders had imposed them. Generally, all of those with a big voice (media and politicians) would gladly wipe out American jobs in exchange for greater profit. This is short-term thinking, ignoring the slow collapse of the nation and the changing balance of world power.
