Kenneth Galbraith, discredited liberal economist, unpersuasively argued in his text "The Affluent Society" that the average consumer's cupidity is so great, that effective advertising would induce the masses to purchase anything.
On the contrary, Columnist George Will has argued time and again. Advertising interest a beer drinker to drink a different beer. Whether he will or not is a matter of inner conjecture and cost-analysis, a process which many elitists dismiss as non-existent among the many diverse human beings who are not as educated as the liberal academics and intellectuals.
Increased upgrades and technological advances have made individuals more market savvy, not less; more precise in their consumption, not flabby and self-aggrandizing. Internet programs like YouTube can expand the political and spiritual imagination of a person or cause it to contract, depending on the choices of the individual, not the application itself.
The prophet Daniel foretold of this explosion of knowledge:
"But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased." (Daniel 12:4)
Now, the book of human potential is opened and ever expanding, with mankind moving about by plane and traveling the whole world through the World Wide Web.
For the record, the ultimate "gizmo" is not the human mind, but the "Ruach", or the Spirit of man, animated by God to appreciate His wonders and adore Him as Lord and Creator.
