I am not opposed to the tax rises needed to make social security more effective, but if benefits won't be tied to wages, why should funding come out of special surcharges on wages? If we're going to break the logical connection between the wage surtax and social insurance, let's end the surtax and move social security obligations and funding into the regular budget, so that ALL sources of taxation are used to fund SS.
