No you're not. ;)
If they define it, people can/will disagree with it. If they don't, they can't/won't.
Or, think of it this way: how many studies with similar outsets but which included a real attempt at a definition for 'ethical' do you think go viral enough to a) make it to HN, and b) get 46 upvotes in 60-119 minutes?
By contrast, the quantitative psych-influenced approach is to pick a proxy variable and measure it, either in the lab or in the field. Much less work, and many people will actually think that style of work is more scientific (it has numbers and p-values). It also makes for better definitive soundbites, because it states a bold conclusion that it doesn't qualify with the dozens of caveats you'd find in a year of real investigation. But it's also considerably more superficial and at risk of measuring based on problematic choices of categories and proxies.
Thanks for the perspective.
Anecdotally, I come from a low income family and witnessed first hand the dissonant beliefs my parents held, that materialistically and socially benefited the rich at our expense, personally, and as a class.
It comes as a real surprise that it is that obvious to you. Are you from outside the United States? Perhaps that may be true in a society that has a shred of class consciousness, but certainly not here.
