Caymen, that post above is all good, and with the details you have added makes me understand what you probably should have said. It also shows why general claims that speak in the most abstract of terms can often not be backed up.
Your original statement was simply too vague, IMHO. You originally said:
there is no way ANYONE could live off $12/hr WHILE paying for health coverage and saving for retirement.
That original statement only listed three circumstances: Make $12/hr (referred to as "that pay), must pay for medical insurance, and save for retirement.
That was it. However, along the way, you added "making it", and began to define what that meant to you. Once you quantify and qualify in that way, then your abstract, generalization is now specific and can be more directly validated (or invalidated). However, that then becomes an entirely different claim and statement. You can't really "stand by your original claim", because it is no longer the same claim. It has morphed, probably towards what you meant to say or should have said, to be fair. Regardless, it is no longer the same statement.
You have gone on to say what you mean by "live", and "making it", and those qualified your original statement. When you do that, you take something that is totally abstract and subjective and give it specific meaning. Then, once that specific meaning and circumstances are added, then YES, I can agree that for THOSE circumstances $12/hr won't be enough.
Regardless, back to your original, unqaulified statement. There are definitions of living, and there are standards of living, in which $12/hr would be enough to meet the two criterias you submitted. You just don't seem to agree that those standards and conditions are what you meant in your abstract statement. However, since you never qualified in the first place, your original statement is (arguably) easily proven false.
The morale of the story: Say what you mean, mean what you say, and use a qualifier or two to make it clear to the reader that there is more going into your statement than you are presenting.
A simple restating as follows goes a long way:
I believe there is no way ANYONE could live off $12/hr WHILE paying for health coverage and saving for retirement and live on their own, living what most would agree is a reasonable lifestyle.
Just a modest restatement like the above will engage the reader. The reader will instantly recognize this to be an opinion, not something presented as fact. We love to be presented facts that we can assess the validity of and embrace or challenge. We don't do that so much with opinions. Second, it introduces the term "reasonable lifestyle", which the reader may take as an opportunity to ask "what do you think a reasonable lifestyle is?". Then it becomes a constructive dialogue, not an offensive/defensive debate.
Presenting vaguely defined opinions as black and white facts will almost always start a pi$$ing contest online, or even face-to-face.
