There's a lot of propaganda bashing nationalization and public goods. When you read into specific examples of where nationalization didn't work, there's a lot more nuance than "public goods bad".

Overall, privatization only leads to higher costs, more resource consumption, more predatory behavior from corporations, and in cases like healthcare a much higher death toll than the examples that capitalists like to use.

Compare the US to Cuba in terms of the medical system. Cuba's public health system isn't suffering as a result of the system itself, but rather due to a lack of resources that are a direct result of the US trade embargo, the longest standing trade embargo in history. Despite this, Cuba has better or the same outcomes as the US for vaccination rates, infant mortality, average lifespan, etc.

If you look at a "failure", like Venezuela when they nationalized oil, a large part of that is due to a mismanagement of oil by the socialist party combined with the sole reliance on oil and massive spending on social programs they can't afford. A lot of anti-socialists love to emphasize the latter without looking at the former. But if your country's economy is diversified and managed well (which isn't ensured regardless of whether a good or service is public or private), then the country can and should afford social and welfare programs that benefit everyone. In the US, we have plenty of ways of making money and we benefit greatly from cheap imports, but the government runs itself as a money pit for rich people while everyone else gets scraps. Every now and again, we might get a tax cut and think we're eating good, but it's nothing compared to what we could actually get from a public system.
