If I may offer my two cents:
Trump's current goals in support and defense of large corporations are what I would call the opposite of being a liberal. In both the classical as well as the political sense.
I believe people who were the foundation of classical liberalism, such as Thomas Paine, Rousseau, Locke, etc, were proponents of individual freedom, right? I don't see how giving more money to amoral, inhuman entities concerned solely with self-preservation and profit can be considered promotion of individual freedom. If anything that empowers them to take more freedom away by concentrating wealth.
And since empowering corporations is pretty much the exact opposite of what will provide stable conditions for people at the working class level, I can't agree with him really. As a liberal/leftist in the definition of someone who supports the working class (rather than the skewed definition propelled onwards by the mainstream), I thus see no reason to follow Trump, even if he claims on camera to be a populist. Reaganomics has not worked to bring the wage gap together, and I doubt Reaganomics 2.0 will do the same.
