Why is Helium so expensive?

Could you possibly explain to me why the price of Helium is so exorbitant? Is it due to its limited availability in nature, or is there some other underlying factor driving up its cost? Given its usage in various technological applications, I'm also curious as to whether demand outweighs supply, leading to its high market value. Additionally, do you think that Helium's high price will persist in the future, or could there be any potential factors that might lead to a decrease in its cost? I'm eager to understand the economics behind this enigmatic element.
