As a socialist economy. The Party for Socialism and Liberation outlines what they believe to be a realistic course of development in their party program. But, in short, it means that the large firms and key industries should be nationalized (as well as the small and medium firms as those grow to levels that central planning works more effectively at), colonized peoples like indigenous and black Americans will take priority, decolonialism will be an important task, as well as working to eliminate imperialism as committed by the US.
A lot of that is easier than it sounds, the US can save a ton of its current productive capacity by nearly eliminating its massivrly over-inflated millitary expenditure, and focus its industrial capacity on re-industrialization, green energy, and necessary infrastructure improvements like high speed rail.
Democracy will also be extended to the economy. Local governments will have ballot initiatives that can be voted on, there will be strict control of private capital (as long as it still exists) with regards to political freedom and influence. The central government will focus more on economic planning, likely copying something like the Five Year Plan model, to ensure a cohesive and comprehensive shift from a heavily fossil-fuel and car-centric financialized economy into a green, industrialized, socialist economy.
Obviously, queer rights, women's rights, and minority rights will be expanded and absolute. Education, healthcare, and even housing can be made eventually to be free at point of service. Employment will be expanded through government infrastructure programs, training, and other important factors for social mobility.
In rural and poor areas, there will be special attention. Impoverished communities will recieve massive infrastructure expansion, fixing, and job training so as to boost these economies and improve their life metrics. This will be similar to what China did to fix their gap in rural and urban development.
That's all general, and fairly abstract, because it must be until we get there. Join an org like PSL. Read theory, here's an introductory Marxist-Leninist reading list I made, targetting radicalized but new leftists. A better world is possible! ☭
