I'm not American but it's my perception that the right and left's position on corporations and laborers is opposite in the US than it is elsewhere, e.g. the E.U.
The left seems to be mostly fine with big corporations becoming larger and larger. They don't seem all that worried that a company like Microsoft has grown 20x in market valuation in the last 4 terms (75% of which ruled by democrats), nor do I see them overtly worried about the implications of having 6 USA companies worth over 1 trillion dollars and the sheer power over people and government that represents.
What they're going after is rich
people, not corporations, hence the "eat the rich" rhetoric.
At the same time we see big corporations happily following through with all the left-leaning social stuff like positive discrimination and DEI programs, celebrating pride month and all the other types of virtue signaling which the left has successful sold as "basic human decency" throughout mainstream media.
And then on the repulicans' side,
you have the biggest labor unions in the US appearing in their conventions.
That said, I don't think it's weird anymore that super left-leaning places like resetera or even reddit have become shills for mega-corporations. They'll love Microsoft unconditionally as long as their promo videos have people announcing their pronouns, there's a rainbow logo during pride month and they
greenwash claim they'll fight carbon emmissions. They don't seem to care about the level of influence the three $3 trillion companies driving AI developments can have in their lives.
It's just the way it is on the US right now.
