The 3 tenets goes as follows:

Anti-capitalism, anti-imperialism, and anti-reaction

1. Anti-capitalism:

We are against the large landholders, industrialists, and financiers, otherwise known as capitalists, who own everything in our society, through private property, and suck on our surplus value through rent, profit, and interest en masse, and go so far as to bust labor unions, decrease real wages through lobbying economic policy and so on.

Their dominance lies in the fact that they control the economy in this way, and thus shape society, government, culture, and many other social forces and institutions... Thus they, the capitalists, are the economic base and the things they control, the superstructure, as a broad front of rentier classes...

Edited:

This is not even including "unequal exchange" or resource and labor extraction in the Global South, which has been ongoing for hundreds of years, now developed from colonialism to neo-colonialism, which has the support of compradors and other allied reactionary local economic interests, such as Pakistani feudal dynasties.

Let alone its resulting political policies that accelerate it such as austerity policies, privatization, IMF restructuring programs, higher interest rates, et monetary policy

This not only wreaks economic, social, and environmental damage in the 3rd world's economic sovereignty and self-suffiency, but effectively decrease the potential of labor and welfare's struggle for better conditions in the imperial core, such as for real wages and pensions, and employment, due to offshoring of labor, if not property to countries like India et Indonesia, which overall causes the de-industrialization of the west, at the cost of both working classes of the Global North (the West) and Global South (3rd world)

Note: despite this, there is a material stake of the Global North's working class, upon this exploitation, due to its promise of fulfilling their needs, if not some temporary luxury... nonetheless, this is a sunk-cost ideology promoted by the ruling class

Our results indicate that most of the North’s excess consumption (58% of it) is sustained by net appropriation from the global South; without this appropriation, material use in high-income nations would be much closer to the sustainable level.

So, what's a potential solution?

'If we stop diverting 130 cents of every new dollar generated to the rentier class, we can afford to obey a moral mandate to bring economic activity back home, which creates a rising tide for wages and living conditions." ' - @HakFoo@lemmy.sdf.org

2. Anti-imperialism,

We are against the dominant west, which is led by the U.S.A, with its military and economic domination of the world, especially the latter upon the Global South, who has hoisted regime change efforts, through the CIA's puppets, such as the USAID and NED, and other western-allied 'NGOs', with its puppetted anti-communist pro-western lib and con politicians, if not junta military collaborators, who come in the form of the EU, NATO, and the Quad...

Edited: This is the raison d'etre for national liberation forces, if not critically-supported anti-western lesser-dominant yet powerful forces who've been demonized with atrocity propaganda, like the People's Republic of China, if not modern-day Russia, the latter of whom has mainly been anti-western by opportunity and circumstance

3. Anti-reaction,

We are against those who oppress LGBTQ+ people, fetishize and humiliate People-of-Color and ethnic minorities, and uphold many hierarchies that justify the economic base of reaction, to make itself look natural and immutable...

tl;dr:

If you oppose at least two of these, you ain't left....
