In 2011 the median income was around $23. This is calculated based on 22 work days per month and 8h per day and taking into account half a month's worth of the "holiday salary" we have. I used 1,33 as the exchange rate because I don't know what the average EURUSD rate was in 2011.
The monthy median salary was 2890€ in 2011 which equals 36125€ per year (12,5 * 2890).
There is no state-mandated minimum wage, instead the different industries may agree on a minimum wage with the unions for that industry only and these are generally kept in line with inflation.
