How far does Lifnei 'Iver extend? Earlier versions of this question led to a good deal of speculation of how an individual should respond to issues of public policy and business that may be contrary to Halachah.
But I wonder if the basic premise starts with Lifnei 'Iver or if a different issue, perhaps just about trying to create a better society (and what that means is its own question, perhaps), is really at the root.
So here's the question:
Does Lifnei 'Iver even apply when it comes to one's taxes and immediate business functions that are removed from, say, immediate sale of a product or immediate employer/employee functions (like forcing an employee to overcharge or deceive a customer)?
Less controversial examples of potential Lifnei 'Iver implications, if it does apply:
* Government engaging in unjust wars
* Working as a marketing executive for McDonald's Corporation
* Working on the campaign of a political candidate who holds some views that are contrary to Halachah (or even one such view).
