Disclaimer: I only tacitly endorse the minimum wage, i'm typically more sympathetic to guaranteed minimum income schemes (even some rightwingers like Milton Friedman advocated such schemes), but since it's a political non-starter i DO think minimum wage laws are better than the free market ideal of NOT HAVING any. And actually the minimum wage argument looks a lot better considering recent studies and real world effects:
First, lets take a case study of Hong Kong. Hong Kong is often used by free market advocates as one of the best examples of what capitalism has to offer. It's consistently rated as one of the most business friendly countries, if not THE most friendly business friendly country in the world. It has a slightly higher purchasing power parity than the United States.
Recently, they raised their minimum wage... to $3.90 an hour. Even by advanced western standards, this is a paltry sum. But here's the kicker: This new minimum wage raises the hourly wage of
10% OF THE CITY'S WORKERS. That means those people were making LESS Than that (looks like $3.64 at the older minimum wage). Without it, the 'natural' minimum wage is most likely to be even
LOWER

If we took $3.90 and inputted it into this calculator to get the annual wage, you'd get a salary of $8112 a year.

That isn't even enough to live on in some developing countries. Hong Kong is one of the most expensive cities to live in as well, so the argument that workers would naturally demand more money and wages would naturally rise is a lousy one. People would rather take jobs
even if it means it doesn't pay enough to get by rather than not have one. It's even shameful by US standards where the federal minimum wage is $7.25 and goes higher based on state and city laws (highest i think is around $10 an hour in san fran). Nevermind countries like Australia with a $16 an hour min wage.
Lets take a look at another experiement: the UK. Recently they upped their minimum wage as well, except it's more in line with western standards, to around $9.64 an hour. There were fears that this would create unemployment, except those fears were unfounded and it benefitted not only the minimum wage earners but PEOPLE ABOVE THEM, which actually had the effect of decreasing income inequality:

Here's another study that showed that increasing minimum wage in the retail/food industry in the US had no negative effects on unemployment.

It seems when we take a step back and look at the real world, the negative effects espoused by conservatives are way overstated (or even nonexistant) and in fact the positives overwhelmingly contribute to society as a whole.
