Mandatory ethics classes don't change the fact that asshole "Tech" bros don't pay attention to them.

The people who said "This is bullshit" in my ethics class are the ones who went to work at facebook and such so they could be rich. They don't care that you get hurt in the process.

Education can only improve a situation caused by lack of education. Most people doing shitty things aren't doing it because they don't know it's shitty.

You see people here on HN making up rationalizations all the time because they know it's shitty. They just don't care that they cause harm. They were raised by people and society to think it's okay to harm someone for your own gain because that's basically what America has advertised for 50 years.
