What sets us apart as 1st world countries is that we have the capacity to ensure a decent minimum wage. If your country does not have a reasonable minimum wage or employment laws that offer protections to workers then that sounds to me like exploitation.
$16AUD in Sydney is probably something like $8USD in Ohio. It's not really a fair comparison to take AUD in an expensive area and compare the wage to USD in a country with a lower cost of living. I mean, Japan doesn't look down its nose at Australia because they get 50 times as many units of currency per unit of time - it's a nonsense comparison.
Talk of "there will always be very low paid jobs that need to be filled" and that "high minimum wages hurt the poor" is the usual bunkum spouted by neo cons.
Then refute it rather than attempting to discredit it without adding anything.
I think you'll find that Aus and the US are not as far apart as you think. Maybe only housing, energy and petrol costs distort the comparison. Food might be a little higher here but it is still relatively cheap. I'm certainly not talking about absolute currency values. Aus/US is almost 1 to 1 anyway. Aus/Japan is 1 to 100, and prices differ accordingly.
Regarding the second part, I'm not necessarily barracking for the other side. Indeed the Left has a lot to answer for regarding union wage negotiations. Truth is I am yet to see any non-partisan research that proves a definite link between minimum wage and economic outcomes.
Since no one on the right ever advocates strongly for a min wage increase, and no one on the left ever advocates for a cut, I can be pretty sure that I should ignore both sides. If you don't ignore them then that is up to you.
Let me tell you how the minimum wage is set in Australia. For the past few decades the Business Council and the Trade unions submit a number to the industrial tribunal/authority, being the increase that should be granted per week.
Unions always say ~$25, business always says ~$5. The increase always ends up being around ~$15 per week. No joke, this is how it is done. And we have had 22 years of uninterrupted economic growth.
