Is the retirement age the same in every country? Is there a difference in pensions?

First of all, let's take the United States as an example, which many people think is relatively rich and powerful on the surface. In the case of normal retirement in the United States, the American Social Security Bureau will set different retirement ages according to different birth dates. For example, for those born before 1937 and 1937, their retirement age is required to be 65, but for those born between 1943 and 1954, their age is required to be 67. And our neighbor Japan has also made great changes in retirement age. In the 1970s, Japan initially set the retirement age at 55, but in the 1980s, Japan extended this age by five years, reaching 60, and today it is 65. But for Japan, many women will not choose to retire at normal time, because many women in Japan will choose to quit their jobs and return to China after marriage. Next, let's talk about Switzerland. Swiss welfare institutions are among the best in the world. Switzerland is recognized as a high welfare country, and they have a very perfect social security system. In Switzerland, if you have a child under 8 years old, you have the right to work 6 hours a day. Even if you lose your job, you can get money from a very rich country. It can almost be said that in Switzerland, you can eat something without working. The retirement age in Switzerland is related to their average life expectancy. Switzerland is recognized as a long-lived country in the world. So Switzerland is one of the first developed countries in the world to retire at the age of 65. And the amount of pension is actually different. Take China as an example, this is mainly related to the grade when we pay social security. At present, social security is divided into three grades, and the fees paid by each grade are different, which leads to different amounts of pensions for people in the future.
