...but lets start with Germany
The Public Retirement Insurance System, which also includes survivor and disability benefits, has been dominant. Participation is mandatory for employees, with each worker assessed for a sum based on annual earnings. Premiums are deducted by the employer, with the employee paying half and the employer half. Starting in January 2012 the premium is 19.6 percent of the gross monthly wage or salary. This is assessed on monthly incomes up to a maximum of 5,600 euros (67,200 euros a year) in the west and 4,800 euros (57,600 euros a year) in the east. Retirement now normally begins at age 65, though it is to be gradually increased to 67. Contributions to the plan are also to be increased, and maximum pensions eventually reduced from 70% to 67% of net pay.
