工作價值觀影響一個人對工作投入心力的表現，和對社會流動與公平機會的看法。西元2000年後，臺灣民眾在面對技術時代的更迭、經濟環境的變換、高教普及等現象造成的社會結構下，「愛拼才會贏」臺灣精神是否依舊存在？以及在面對已固化的社會結構中，高學歷者是否有更高的信心可以憑藉個人努力等因素，突破「貧富差距」的階級之牆。年輕階層工作者面對付出之時間、心力與期望值不相等，是否如媒體輿論所述的「躺平」，失去對社會流動的信心？
本研究使用並合併台灣社會變遷基本調查資料中的2000年、2010年以及2020的綜合問卷三個期次資料，探究在2000年後，臺灣民眾在吃苦耐勞會成功的工作價值觀及對貧富差距、階級流動認知的變化趨勢。研究發現從2000年後的20年時間軸線變化來看，臺灣民眾對於「吃苦就能成功」的個人信念趨勢正隨著時間推演，逐漸減弱中。其中，教育程度較低者、年輕階層及女性較為認同「愛拼才會贏」的拼搏精神。教育程度在國中以下者，更是顯著性地深信。整體而言，有六成以上的臺灣民眾對於已固化的貧富差距認為努力也跨越不了，並不認同努力可突破財富界限。然而，教育程度較高者、年輕階層及收入高者則認為努力可突破貧富差距，仍相信有機會進行階級流動。而29歲以下的年輕階層一直都相信努力可以突破貧富差距，數據結果破除媒體輿論框架於年輕階層的「躺平」標籤。此外，臺灣女性比男性更抱持著「吃苦就能成功」的內在信念，並有顯著性差異。

Work values influence a person's commitment to work and their views on social mobility and fair opportunities. After the year 2000, the Taiwanese people were faced with the social structure caused by changes in the technological era, changes in the economic environment, and the spread of higher education. Does the Taiwanese spirit of "You will win if you love to work hard" still exist? And in the face of a solidified social structure, do highly educated people have greater confidence that they can break through the class wall of the "rich-poor gap" through personal efforts and other factors? Faced with the unequal demands for time, effort and expectations among young workers, are they "living flat" as the media said and losing confidence in social mobility? Our study which selects the data from three periods of comprehensive questionnaires in 2000, 2010 and 2020 is from Basic Survey on Social Change in Taiwan. The purpose is to study the changing trends after 2000 of the work values for Taiwanese people who will succeed through hard work and their attitude towards the gap between rich and poor. The study found that judging from the changes in the timeline of the 20 years after 2000, Taiwanese people's personal belief trend in "success can be achieved by enduring hardship" is gradually weakening over time. Among them, those with lower education levels, young people and women are more likely to agree with the fighting spirit of "If you work hard, you will win." Those whose education level is below junior high school are even more convinced. Overall, more than 60% of Taiwanese people believe that the solidified gap between rich and poor cannot be overcome with hard work, and do not agree that hard work can break through the boundaries of wealth. However, those with higher education levels, younger people and those with higher incomes believe that hard work can break the gap between rich and poor, and they still believe that there are opportunities for class mobility. The young people under the age of 29 have always believed that hard work can break the gap between the rich and the poor. The data results break the media public opinion framework's "flattering" label on the young class. In addition, Taiwanese women hold the inner belief that "you can succeed if you endure hardship" more than men, and there is a significant difference.
