This very well educated young man is suggesting to cap the wages in the IT sector because these are getting too high for the industry and therefore might hurt smaller/middle sized companies. Especially developers should not be allowed to be paid more than €100k per annum.
Being in the industry this in fact a good salary but we also have a full tax rate of 52% and a 2 bedroom flat incl all utilities is easily around €2k in the major cities where those jobs are usually offered. That would mean that someone making this salary has to pay roughly 46% of his after tax money for rent.
