That would imply, that (globally) we spent significantly [EDIT: remove -less-, insert:] more on advertising before the advent of personalized targeting.
Got confused while writing by the observation that ad expenditure is rising year after year. So clearly, the "savings" allegedly attributed to personalized targeting have not translated to advertisers.
Why would a reduction in advertising costs equate to lower consumer pricing — if there's a better margin to be had instead?
Products with no fancy marketing, frequently coming from smaller local companies, bring much better price/quality ratio.
The sponsoring of brainwashing is worse than the value loss.
