I agree on what the mall says, because the more you spend the money, the faster it will circulate and the faster the economy will grow and it helps to generate more jobs.

And according to Karl Marx:

In the first instance real circulation consists of a mass of random purchases and sales taking place simultaneously. In both purchase and sale commodities and money confront each other in the same way; the seller represents the commodity, the buyer the money. As a means of circulation money therefore appears always as a means of purchase, and this obscures the fact that it fulfils different functions in the antithetical phases of the metamorphosis of commodities.

Money passes into the hands of the seller in the same transaction which transfers the commodity into the hands of the buyer. Commodity and money thus move in opposite directions, and this change of places – in the course of which the commodity crosses over to one side and money to the other – occurs simultaneously at an indefinite number of points along the entire surface of bourgeois society. But the first move of the commodity in the sphere of circulation is also its last move. [1] No matter whether the commodity changes its position because gold is attracted by it (C—M) or because it is attracted by gold (M—C), in consequence of the single move, the single change of place, it falls out of the sphere of circulation into that of consumption. Circulation is a perpetual movement of commodities, though always of different commodities, and each commodity makes but one move. Each commodity begins the second phase of its circuit not as the same commodity, but as a different commodity, i.e., gold. The movement of the metamorphosed commodity is thus the movement of gold. The same coin or the identical bit of gold which in the transaction C—M changed places with a commodity becomes in turn the starting point of M—C, and thus for the second time changes places with another commodity. Just as it passed from the hands of B, the buyer, into those of A, the seller, so now it passes from the hands of A, who has become a buyer, into those of C. The changes in the form of a commodity, its transformation into money and its retransformation from money, in other words the movement of the total metamorphosis of a commodity, accordingly appear as the extrinsic movement of a single coin which changes places twice, with two different commodities. However scattered and fortuitous the simultaneous purchases and sales may be, a buyer is always confronted by a seller in actual circulation, and the money which takes the place of the commodity sold must already have changed places once with another commodity before reaching the hands of the buyer. On the other hand, sooner or later the money will pass again from the hands of the seller who has become a buyer into those of a new seller, and its repeated changes of place express the interlocking of the metamorphoses of commodities. The same coins therefore proceed – always in the opposite direction to the commodities moved – from one point of the circuit to another; some coins move more frequently, others less frequently, thus describing a longer or shorter curve. The different movements of one and the same coin can follow one another only temporally, just as conversely the multiplicity and fragmentation of the purchases and sales are reflected in the simultaneous and spatially concurrent changes of place of commodity and money.
