It depends where you live. In the Puget Sound region of Washington you can't find a house to rent for under about $2500 a month, or one to buy for under $500K; most are much more. Gasoline is over $4 a gallon.
I'm sure some regions are much cheaper.

But a fair wage depends on the employers ability to earn a profit. If the employer can't make a profit the notion of a "fair wage" is irrelevent.

do I LIKE it? No.

Lots of people make enough money. They are broke because their money habits.

I think a fair wage depends on a few factors.
If you make enough money to pay the bill afford some hobby/it's and put money away that's typically a fair wage.
Depending on your occupation may have something to do with a fair wage.if your in a job where it's harmful to your health or a very physical demanding job you should be compensated accordingly.

If picking berries is similar to tying rebar, it wouldn't be cheap.
