The victim is a mix. The previous owners, the people would have bought there if the Amazon's employees did not, and the people who now are going to buy in that neighborhood in the future.
How does that make them a victim? They weren't forced to sell at any price. That's real estate and the article says they are net new construction.
Also, Amazon has thousands of employees in NYC already. LIC is close to Midtown Manhattan, a few subway stops away and is a neighborhood full of new construction.
It makes sense for any employees to buy there regardless of any situation...doesn't?
Since when is "Buying a nice apartment in a desirable neighborhood near work" a suspicious or criminal thing? Geez.
By this logic, would it not be immoral to engage in any trades when there exist information asymmetry? There will always be "victims" who do not make a profit because they made a bad investment.
A person losing money due to insider trading has almost certainly invested in a company that was not worth what they thought it was. If they’re a victim, then whose victim are they really? I have a hard time blaming the insider trader.
