Advertising. That's the problem. Computing has become a branch of the ad industry. What we need is a big tax on advertising and marketing. In the US, it doesn't create more demand, because most people are spent out. It just moves demand around. So much of that effort is a net lose that pushes prices up. (This might be politically possible during an "anti-tech" Trump administration.)
Advertising is a big part of it, sure. But it is merely a component of late-stage capitalism. Using psychological manipulation to sell products is the most profitable way of sustaining a business we've invented yet, but we have many other ways to unscrupulously exploit one another for financial gains. Humanity has been doing that for millennia, and we've gotten very good at it.
Which is why it's something to tax. As opposed to more productive endeavors.
