Demand for goods and services creates jobs. Period.
Owning a business is a job. No demand for goods and services.......no jobs.
Of course..........except for the fact that business owner MUST first create the goods.
You are next going to argue that the egg comes before the Chicken
Depends... the RETAIL owner does not create anything, other than trying to increase demand through advertising the product....which is just creating hype! She buys the product based on what her/his projected demand will be for it..... she/he projects the demand by analyzing 'sales' every which way but loose....even if it is a new product being introduced in to Retail, she has some statistics of similar items and similar introductions to project the demand/the sales for the period she is buying for.... along with other analysis like, how has the Store she is buying for been trending in their sales ....up or down? Has the population around the store increased or decreased? Has the demographics of who lives there changed? Is it now an 'older' generation living there or a 'younger' crowd moving in?
Just so so many things are analyzed to project the demand before one order is sent to the manufacturer or vendor or rather, before one dime is spent!
Projected DEMAND is EVERYTHING in retail.....if you get it right...then you are ''in the money''.....
In Wholesale/Manufacturing....where the product development happens...they too are driven by numbers for the most part....they have an item, that has been selling well, but is looking tired or getting dated, so the product marketing/development manager directs the designers and engineers to come up with a replacement for their tired looking item.......... giving them direction on how they would like to see the Designer and Engineer change it...........i.e. I'd like to see the widget lighter in weight, while keeping the same size, with additional metallic colors in the line, with the ability to do X Y and Z, and need the 'cost' to be 'X' once you've developed it..... then they come back with their prototypes, the product development manager and others say yea or nay to the different parts of the design and then a second round of prototypes..... etc...
THE Engineer finds the factory capable of manufacturing the item at the cost that was needed to wholesale it at the right price so that it had a chance, with its retail price, of selling....usually China, Hong Kong, Taiwan, Indonesia or Brazil, in the industry that I was in..... When I was young, and just beginning my career, most vendors were from the USA.... some from Italy and Spain....but very little business was done there.... now, due to laws, treaties, etc....hardly anything is ever manufactured in the USA in this industry.
THE wholesale industry does not buy upfront... they tentatively book a factory line to make the goods, they may purchase some of the materials upfront, but in general, they produce samples to give to their reps and to bring to Market/Shows, where they get feedback from the retail buyers on what the buyers estimate they could buy on the item.........before they start manufacturing line runs of the item.
So, this ''creating a widget'' out of thin air, truly doesn't happen, but very very rarely..... the Apple, Ford, and Microsoft etc are rare..... even entrepreneurs rely on demand and projected demand, before creating their new invention or opening their new business and all along the company's success, demand or projected demand is the DRIVER.
Demand is what gives the spokes to the wheel and makes it turn, in both wholesale and retail businesses, 90% of the time...imo.
What I am getting at, is that as a person, who has worked both sides of the Industry of Retail and Manufacturing....
'Supply' usually doesn't happen without the demand/projected demand, from my point of seeing it.
