"Outperforming" here means extracting as much wealth as possible and consolidating it in the hands of a few. All the while being an absolute detriment to the health of the environment and people it uses to extract said wealth.
Environmental damage is a big one. Basically anytime some cost is due, such as pollution, but corporations ignore cleanup, and thus the cost. That bill is still due eventually, and it’s left to others to pay the price
Bananas. There's a reason they're 69 cents a pound despite coming from Central America whereas apples are like 4-5 times as much and mostly come from US orchards.
What do you mean by "successful?" Is there a metric you want to look at specifically? There are numerous metrics we can track and compare with Pre-Socialist conditions.
As for what countries have implemented "my preferred alternative," this is also an undeveloped fragment. No system can or should be 100% my personal preference, every country has different conditions, and simply copying others isn't how systems are run.
To answer your question, numerous countries have become Socialist. The USSR and PRC are the biggest examples, and for metrics both countries doubled life expectancy, eliminated famine, tripled literacy rates, and generally industrialized as compared to the Tsarist system or under the Nationalist KMT, respectively. They had and have numerous problems, corruption in the USSR and the Cultural Revolution under Mao, but conditions for the average person rapidly improved.
I am not advocating for copying these systems 1 for 1, but learning from what worked and what didn't. It seems that eliminating the profit motive and focusing on satisfying needs through servives like free healthcare and education makes a huge difference in a population.
Exactly so an extremely small subset of the population. Which is why capitalism is not being abolished and no one cares about criticism of capitalism but people gets annoyed when people start trying to implement other systems.
Capitalism won't be overthrown by just convincing people of better. Capitalism is overthrown when material conditions decline due to issues like the Tendency for the Rate of Profit to Fall.
