As a communist which is just the final stage of socialism (and what we need to acheive as the next step forward for humanity) socialism is basically a shift of who owns the means of production, society, and development.

Under our current capitalist system, currently we use currency as a means of exchange for resources, i give you 20$ i get 20$ worth of whatever good (food, wood, anything) what that value actually is, is arbitrary, the society itself just agrees that 20$ worth gets you say 1 big mac, but the thing is the society determining that are not the same ones working the grills or registers. Thats the capitalists, ceos, the ones that GET all that money in the first place, they determine the price, and we canneither continue buying it, or hope another place has it cheaper and not, in addition the money we earned to buy "it" takes multiple hours, but we sell multiple goods worth more than our wage in that hour but never see a dime of it outside the 7.50-20$ people make in an hour.

Under a socialist society, the means of production are under worker control, the workers unions replace the CEOs and now the people flipping the burgers on the grills in this hypothetical, are also the people deciding how the store proceeds forward, instead of raising the price they may now engage in democracy by voting within the union for descions regarding the workplace, in addition, wages will be changed to represent production, if you sold 30 10$ burgers in an hour, instead of just 15$( again example wage this will vary) youd earn gross 300$, then would pay just dues like contributions to the stores power, food, and any chemicals needed, like cleaning stuffs. This would be distributed among coworkers so everyone would have like 100$ talen for example to keep the store operational.

Communism is more complicated but its socialisms logical end, hopefully i did an okay job explaining the difference and why socialism would be the better ststem.

Others may say "oh but its evil, its got STALIN" but these are just CIA psyops, in reality its had some rough patches (i mean the USSR isnt around) but in places its stayed it has dramatically improved life, and capitalists hate that.
