Some (a lot?) of economic activity seems to be self-serving, not making our lives better (and sometimes making them worse). The lockdowns demonstrated that very well. For example: social media (doesn't add anything beneficial, makes us less social); 'influencers'; a good chunk of the hospitality industry; anything to do with crypto.
Very often, free alternatives / those not involving 3rd parties, simpler living, are better for us overall. But if more expensive options are available, we are pressured to take them so that we are not left behind / feel like we fit in / have a social life.
Also, at some point certain things are just 'good enough', and marginal improvements require a ton of effort but don't make life better. For example, mobile phones - an 8 year old phone would work just fine, if not for forced obsoletion. Yet tons of effort go into very marginal improvements, because if you don't do it, your competitors will.
