Many different conceptions of value are employed in different contexts, and more than one conception is employed in economics. But the notion of value that is most fundamental to economics is that of usefulness.

Usefulness isn't some attribute independent of context, nor does anything have the same usefulness to one person as it does to another. When context changes, value changes. When a thing that had value is moved, it does not carry its value with it; rather, it takes-on a new value associated with its new context. When a thing that had value moves from being the property of one person to being the property of another, its old value is not delivered to the new person; rather, it takes-on a new value associated with its new ownership.

Prices represent a somewhat different sort of value. Prices are quasi-quantified prioritizations, under which things may be exchanged. But, however prices are formed, they work only to the extent that they promote any exchanges that are useful to those potentially making the exchanges, and discourage any that are not. Ostensible prices that do not do so will be ignored in markets, and bring-about economic failure in other systems of allocation. Market values — prices established by markets — are those that conform to the priorities of the parties who choose to exchange. Market values, though different from usefulness, must be informed by usefulness, and thus must thus reflect the contexts of the things priced.

Monetary prices are quantities of money but not measures of market value.* Prices are first-and-foremost rankings, and treating them as quantifications has limited heuristic value; a thing may be rationally priced at $1000 without its being 1000 times as useful as something rationally priced at $1. And, though the first thing may be rationally priced at $1000 in some context, if the context is changed radically, the thing may cease to have any usefulness, so that its price should be 0. Because of contextual issues, one cannot even say that if the price of one commodity is n that of another then it will always be possible to buy n times as much of the latter as of the former with the same quantity of money.*

A great deal of the wealth in to-day's world is in the form of financial claims that have no meaning what-so-ever outside of the context of a market. If the market is eliminated, then these claims would have no usefulness and hence a rational price of 0. If the markets in which these claims might be used were somehow preserved, but the claims were seized and redistributed, then their new contexts would correspond to greatly diminished usefulness, and their rational prices would then be much smaller.

The great fallacy of popular notions that poor and middle-income people might be significantly enriched by a large-scale seizure and implicit or explicit redistribution of wealth from billionaires or from the 1% or whatever is the notion that the present prices of the seized wealth reflect an intrinsic economic property of the things seized, which property will be delivered with the things as they are transferred. Instead, the old value will evaporate, and the new value will often be 0.

This point is true even in cases in which the assets seized are not financial instruments. Imagine a community given a Lamborghini Diablo. It had more value than a Honda Fit to the millionaire who owned it; but, for the community, the Honda Fit could be more useful than a Lamborghini Diablo. The respective prices prior to redistribution were plainly poor reflections of what would be the values in the new context.

Wealth is destroyed not only when things of value are seized from the very wealthy and given to those less wealthy, but when there is any sort of large-scale redistribution; including that from the lower- and middle-income groups to the very wealthy. But further indiscriminate redistribution, as by income group, will not restore the wealth lost to past redistribution, and even in hypothetical cases in which only actual perpetrators are penalized and actual victims are compensated, there may be further loss of wealth as such.

So, no. There isn't enough money for the dreams of the Occupation movement nor for the promises made by candidates such as Bernie Sanders, because money doesn't work that way. And there isn't enough wealth, because wealth doesn't work that way. The accountings that claim otherwise are crack-pot.
