Do the billionaires actually have the money?

I've often wondered if there is something I'm missing about how wealth is understood at the billionaire level. Most of their value is not in cash so isn't what they are worth more of an appraisal?

I understand scapegoating billionaires. But I wonder how could we expect them to pay for things when they don't have cash, or with value that isn't real but rather projected. 

How much of the 100 billion in Jeff's worth is translatable to increases in Amazon wages? How would that process work?

I thank you in advance and am not looking for political answers but distinctly economic ones.

We'll take your Jeff Bezos example. The majority of Bezos's fortune is held in Amazon stock. If Bezos wanted to turn his stock into cash, he would simply sell his Amazon stock. However, because he owns such a large amount of Amazon stock, if he decided to dump all of it at once, it would hurt Amazon's share price and lower his net worth in the process. So he'd have to sell it very slowly over time to realise it's full value, assuming the stock price held stable over this time period which is a big assumption. If you taxed his wealth highly enough, then you'd see him have to devalue Amazon stock by selling off enough shares to cover the tax burden.
