That's the funny thing. Trump's trade policy is leftist populism through and through. And now many of the life-long capitalists are like "you know, maybe the free-market isn't great. Let's give protectionism a chance!".
This is more or less hate speech. You're trying to paint capitalists as Laissez-faire.
Capitalists are against unfair competition practices, no matter whether that comes from monopolies, intentionally operating at a loss to bankrupt competitors, mercantilism, subsidizing your industries, environmental advantages from unregulated industries, currency manipulation, and business lead regulation statutes (Trump has a damn good point on what drives environmental regulation).
