That's not what Socialism is, or even Communism. In every existing Socialist state, people have gotten higher or lower pay for different levels of intensity or skill. If getting paid the same is "the problem with pure socialism" then it sounds like it's all cleared up!

Secondly, Social Democracy still relies on Capitalism, which necessarily moves in the direction of increased disparity and centralization of power in fewer and fewer hands. Moreover, as companies spread internationally, Capitalism turns to Imperialism, whereby workers in the Global South are paid a fraction of the wages a worker in the Global North would be paid. This form of hyper-exploitation for super-profits results in dramatically unequal exchange and underdevelopment. Socialism is the way forward, beyond this system of exploitation and eventual collapse.

I really recommend you give at least the first section of my reading list a try.

You're very confident for one who is so wrong.

Wow. Immediately going to the myth of laziness right from the get go.

You're wrapped in arrogance armor, placed there by propagandists. It makes you feel well intentioned, principled, correct, and most importantly, educated. The problem is that the propagandists ensured you were ignorant and dogmatic. Now you have the terrible curse of being ignorant and dogmatic but believing you're knowledgeable and principled.

Just study more history. Read the people that you're scared of like Marx, Engels, Lenin, Stalin, Mao. Just read more and seek after knowledge that contradicts your upbringing. Most Western communists were raised on the same propaganda you were. We all managed to defeat our training by learning more about what's really been happening for the last 500 years and unlearning the lies we were raised with.

You can do it, too.
