Meanwhile, countries like Germany take the opposite tack where labor and corporate interests work together in the best interests of their members and employees, because they know that happy and secure workers are productive workers, and you can hardly argue that Germany is not a successful economy.
You should be careful in the future using Germany as a good example. I know, compared to the U.S., the situation in Germany is still great, but Angela Merkel, and Gerhard Schröder before her, worked hard to implement the same (or similar) policies concering worker's rights and social security as American politics since Reagan.
We also have seen an artificial weakening of unions and employee representatives, we've seen a drastic increase of low wage jobs with less privileges replacing better paid jobs with more privileges, and the success of the German economy in the last decade and a half has been largely due to the export surplus, as in having the wages stagnate to get relatively cheap labor to manufactur products for export, but with these lower wages people can't buy as many products, like products that would have to get imported from other countries.
Normally, this would get relativized by upgrading the currency, but Germany has the same currency as many other European countries suffering from Germany's dumping wages, and these countries with their deficits keep the Euro low for the benefit of Germany.
It's been a public debate for years now that the economic boom doesn't reach the middle and lower classes, as well as the fact that Germany is basically exploiting its European neighbours. Merkel and her fans in the media try to silence that debate with the simplified "Germany is doing fine" statements, as well as arguing that "it's not Germany's fault that those other countries don't produce anything Germans want to buy", but the dissatisfaction is getting stronger, and is only slowed down by the second big political party being too close to Merkel's policies, as well.
You should probably try to find a better place to work. An assistant manager shouldn't be making minimum wage, whatever that minimum is.

Easy to say, but there simply are no better jobs available. I'm preparing for a course of advanced job training right now, and I can't look at the job offers in the papers because it's too demoralizing. All offers in my field are part-time jobs which would be better than minimum wage, but by cutting my hours I'd still be left with a smaller income.
So your boss has given you all the responsibilities he doesn't want for the same pay? That's pretty shitty. I wouldn't stay there another day if I had other options.
At least, you added that last part.
Actually, the owner and the manager are two different people, and the manager can only work inside the budget given by the owner (who only comes by once or twice per month).
