OZ basic minimum wage is around $16 per hour. At todays exchange rate that's $15.0096 USD ... but of course it's not that simple, it depends on age, casual or permanent employment etc so if you're obsessed ...
http://mywage.org.au/main/salary/minimum-wage ... gives the full table.
We have holiday, shift allowances and 'penalty' rates for weekend work etc added to that so it's not clear cut.
Other factors that come into it when making comparisons are:
Our workers in do NOT expect or usually receive tips to bolster wages. It's simply never been done here as a rule although is in some instances.
Our living costs are higher, petrol, rents etc.
Balancing that is reduced costs of 'utilities', especially heating costs as our winters aren't as harsh as in much of the US.
And, most importantly, employers are compelled to pay higher rates for shifts that go past 9-5 normal working time. Overtime is paid at a higher rate. Different pay levels apply to different public holidays (or did when I was working) Example Christmas was paid at a higher rate than a normal weekend. It was a graded rate.
It's far too complicated for me to sort out but suffice to say I wouldn't want to try and pay off a house and raise a family on our basic wage either. I can live on it, (I don't, but easily could) because I own my house, don't go out much, and have only the dog and myself to feed. It would be no life for a younger person.
I worked my entire career at the basic minimum wage salary. But the penalty rates, loadings, overtime rates, and working shifts no one else wanted, and never working the lower paid '9 to 5' shifts, meant I effectively doubled my salary most years.
That seems to be the major problem in the US, lower paid workers have little option to improve their income.
Jackie, that article showing the attitude of employers is scary. There's quite a bit of that here too but the greedier are held at bay a little easier by legislation here. Theirs is a self defeating tactic as eventually no one will work for them and their business will crumble when they not only can't produce, but have no customers who can afford to buy their product.
I'm more right wing than many OZ members but even I have a very poor view of that rip 'em orf attitude in employers.
I like a nice balance in my World. Pay for what you get, and be paid for what you're worth.
I'm an atheist yet base my view of keeping balance between employers and workers on 2 biblical tracts. (Even stopped clocks are right twice a day.

)
"Render under Caesar, that which is Caesars" ... that one is for the Socialists who think the employer owes them more than they're worth.
.. and "Muzzle not the Ox which grinds the corn" which is for the employer who wants to enslave his workforce on a pittance.
What is it in human nature that prevents us ever settling for 'enough'?? What makes us want it all?
Why do we continually risk losing it all by reaching further for that one extra buck?
