This newspaper’s comprehensive foreign media reports, November 25，The official website of the University of Pennsylvania said，Recently, scholars such as Song Xi, associate professor of the Department of Sociology of the school, made a long-term assessment of bet365 offers in the United States。Research results show，Over the past 150 years，bet365 offers of the U.S. population has declined significantly，Especially among those born after the 1940s。Over the past 40 years，Rising economic inequality is not affecting intergenerational mobility as many expected。

This study mainly focused on American men。Research results show，Male youths born before 1900 have more opportunities for upward mobility than their parents did。Because at that time，The United States is moving from an agricultural society to an industrial society，This change has caused the younger generation of male youths to no longer do the farm work done by their fathers，Instead, it entered the manufacturing field，Become a worker、Blacksmith、Mason、Truck Drivers and Salespeople。Compared with their parents，They gained a higher socioeconomic status。But as the bet365 offers prestige of certain professions declines，This trajectory begins to change slowly。Take the cashier as an example，In the 1850s，If you can read、Write、Calculation，You can become a cashier，It was a job with a relatively high bet365 offers status at the time。But as time goes by，The socioeconomic status of cashiers has declined。Like a scientist、Architect、Engineers and other highly professional occupations，Their socioeconomic status will remain stable。

The author thinks，Starting with the Baby Boomers，The relationship between the two generations becomes closer。The economic status of the current generation of children in society is very similar to that of their parents’ generation，And it is difficult to change。In simple terms，Children’s achievements in society reflect their family background。In addition，Although since the 1970s，Income inequality in the United States begins to increase，But bet365 offers trends remain largely stable。Proposed by the author，Promoting bet365 offers through family intervention policies is a difficult task。We will collect more other data in the future，More truly reflects the bet365 offers status of the U.S. population。（Zhao Qi/compiler）
