I suppose this counts as "no room for truth": The left lie about everything, why wouldn't they lie about their fundamental motivations?
The left isn't even remotely what it pretends to be. Outside of a few occasions in the late 19th, early 20th century union fighting, leftism has been an ideology pushed by, about, and for aristocrats. Marx was the wastrel son of an industrial family. Lenin was a nobleman. All their talk about "the working class" is verbal bafflegab to give cover to the nihilistic violence unleashed by their armies of thugs. They really don't give a shit about working people, which is especially obvious in the modern west, but also in their murderous oppression of workers throughout history whenever legitimate working people ever get together to demand rights. The Krondstadt rebellion is a good example. (Polish solidarity, the list goes on...)
They are perfectly happy to set up conditions of slavery and forced labor, such as the white-sea canal project, or the Foxconn factories.
They talk a lot about attacking "capitalists" and large monopoly companies, but what they really have a raging hate-boner for is "the bourgeoisie", which is one of their plastic non-words, but always ends up meaning anyone with a shred of independence. Free-holders, independent farmers, small-businessmen: These people are the backbone of any functioning civilization worth the word. The bright periods in human history are those when most people in society are free and own their own livelihoods, and there is a broad distribution of the ownership of the land and resources, forcing would-be oligarchs and tyrants to take notice of their rights and desires. Ownership is desperately important to a free society - for freedom to exist, people need to be able to own their livelihoods.
Leftists always allege that this is a "transitional stage" that cannot last naturally under capitalism. Then they go about centralizing all ownership in a rigid hierarchical totalitarian state. (And they gleefully murder the independent along the way - the Kulaks were independent small-farmers.) The modern left reserves their contempt for the tradies, for independent tradesmen, for independent farmers, for owner-operator truckers. They actually look down on and despise workers.
If monopolies are a problem, socialism enshrines them in state power and doubles down on them. When leftists get their way, the workers don't get to own the means of production: They don't get to own shit. They don't even get to own themselves.
