Eh. High minimum wage in Seattle is ridiculous because the USA is pretty much an open market. Same reason why people wanting to raise the Belgian minimum wage are nuts in a Europe that contains countries like Poland and Croatia. Yes, a minimum wage should be able to support a person (though not in luxury). Raising minimum wage in only part of a market is stupid and will have adverse effects. You know how many trucks are on Belgian roads? Literally hundreds of thousands (highest amount of trucks per capita in the world.) You know how many of them are driven by Belgian teamsters? ...Yeah, some 5 or so. All the rest are Bulgarian or Polish or, increasingly, Romanian (despite not being part of the EU, we have free traffic of labour with them). I'm not racist or prejudiced against Polish people or any other Eastern European countries, but, unlike in most cases, here it's a very clear "they took our jobs" thing at play. Any job that can be done by someone without a fixed address in Belgium, is slowly being "outsourced" to other European countries, with "consultants" and "temporary assignments" and so on in Belgium. Polish carpenters, Bulgarian plumbers - they're just as capable as their Belgian counterparts (hell, with our over-education, they're often better), and they cost half. And it's, in most cases, legal! Why the * would you hire a Belgian construction worker for €15+ if you can hire a Polish one for €6 + room and board (of course, what passes for "room and board" in construction circles is....Somewhat rudimentary)?
Minimum wage should be enough to live on. Living costs vary around a market (living anywhere in Poland is obviously cheaper than living in Paris). There's bound to be some differences. Make the differences too big and multinationals will go where labor is cheapest and regulations laxest. I've said before and I'll say again that unions etc in the Western world are digging their own grave and being short-sighted by fighting for our rights, when they should be fighting for everyone's rights. A minimum wage in Thailand will do more good to factory workers here than a thousand new law and regulations here.
