On a broad scale, we have moved from a culture of ads as info, to ads that push you to buy whatever the factory produces. This huge supply and false demand for things we don't really need has a huge impact of consumption culture, personal distress - an ongoing feeling that you always lack something, ecological waste and people wasting their hard earned dollars on things they don't really need. God bless ad blockers.
Who gets to decide whether something is necessary or not?
Maslow understood that humans "need" pathways to self-esteem and self-expression. An extensive collection of Marvel action figures could slip through that loophole.
Francis of Assisi lived in abject poverty, and would be a much harsher judge than Maslow, and would probably criticize either of us for bothering to own any electronic devices.
I'm neither a Franciscan nor a Maslowian, but the concept of "human needs" hardly lends itself to immediate and universal agreement.
