In order to avoid the bankruptcy of the pension system, the British government has reformed the system from four aspects: First, increase pension insurance contributions. From the financial year 2011-2012, the contribution ratio of employees and employers will each increase by 1%, totaling as 25.8%. The second is to postpone the retirement age. Regardless of the age at which men and women receive pensions, they will further increase. The third is to reform the occupational pension, stipulating that the second pillar of voluntary occupational pension will become a compulsory occupation from October 2012. Pensions require all annual income of more than 7,475 pounds, aged between 22 and the legal retirement age, and workers who have not participated in any occupational pension plan will "automatically join" the occupational pension plan. The fourth is the establishment of government funding The low-cost national occupational savings trust. The savings trust has an ultra-low 0.3% annual management fee rate. At that time, the third pillar of private pensions, personal life insurance will be more integrated with the second pillar, and the national occupational savings trust platform will be unified. And thus constitute the main body of the British pension. What is the essence of the UK government's pension system reform measures? ['Add more pensions to choose from.', 'Uniform use of the national occupational savings trust platform.', 'Enhancing the attractiveness of the occupational pension system.', 'Increase pension income and save.']
