So the logic here is that if I take a strawberry cake and sprinkle some chocolate on it then that's proof that a chocolate cake is better than a strawberry cake?

Not quite I think. The logic would be that everyone says strawberry cake is the best cake there is, yet every ten years we have to dump a ton of chocolate on it to make it edible so they're asking, was it really that good to begin with?

No, it's proof that chocolate can be a tasty addition.

Left: Capitalism isn't always perfect, sometimes social policies make a better society.

Right: Capitalism is always perfect, socialism is evil even in the smallest amounts.
