It's deliberate. Left-wing ideologies are basically "we don't really benefit from these traditional hierarchies and we'd be better off if we didn't concentrate resources in the hands of a small number of owners so much", which is hard to argue against.

So those who want to keep their power in the current system try to misdirect the debates themselves with "libertarianism" and "neo liberalism" which are both economically conservative ideologies that try to separate the idea of personal freedom from economic ones and ignore that any "freedom" in business is against a background of negotiation leverage, so more freedom in business gives more advantages to those with more leverage.

That first paragraph is also why conservatives put so much attention towards making it difficult to vote, get a good education, or find various supports. They know trying to argue that they should have control of most of the wealth is a losing argument so they go for confusing as many as possible or keeping them busy with their own survival.

Liberal was stolen so libertarians had to find a new word
