For most tech, the design is aligned with the goals of the business that made it. Until you invent ethically aligned capitalism, limited progress can be made.
Ethically aligned capitalism is just regular capitalism with ethically aligned people, no different from the ethically aligned version of any other society.
No. Companies believe their only duty is to protect shareholder value, so that's what drives their decision making, not ethics. As long as we have that problem, it won't matter how many ethical people we have in our society. As of right now, we have plenty of people who want to do the right thing, but can't because they'll lose their jobs.
Blaming people over systems tends to suit mammalian instincts, but it's not constructive. We can change how society is structured, but not what it's composed of.
I'm pretty sure that's called... well, not capitalism.
