Yes it cannot be saved because by nature it's contradictory and exploitative, all of the problems are caused by capitalism because without those problems people would be able to question for another system.
Rather improved, if we destory it, where do we go back to? You can't move forward with removing the ground you stand on
That's a very evolutionist stand, which is proved to do more harm than good to society. There are economic options out of capitalism and communism, for that matter.
If you think that capitalism is going forward or a valid place to start something from, it surprises me that you're even in this community, since even Marx himself abandoned the idea that capitalism was the necessary (although wrong) path to get to socialism.
The progression of humanity was from hunter-gatherer to larger tribes to city-states to eventual feudalism by the late Antiquity all the way up until around 1600. We've not even had any kind of pure capitalism since then, only some hybrids of capital and socialism.
First, what do you mean by "pure capitalism"?
Second, the fact that some "socialism" is mixed into the capitalism is the only reason it hasn't failed sooner.
Is it Karl Marx or is it Ron Swanson's alter ego, Nick Offerman?
Yes.
We see the results of Communism in the USSR and North Korea. Nobody wants that hell.
