Since education policy dictated by the government affects economic activities and value of labor power of a country, it needs to be examined. This paper proposes a simulation model of the relations between education and social stratification, including alternation of generation, based on Bourdieu to examine education policies. The education policies examined are whether there are relations between one’s academic background and his/her lifetime income, and what kind of effects are observed when financial support from grandparental generation is permitted. The main results are as follows: (1) Giving an opportunity to go to college to low-income population improves total incomes and academic skills because going to college is a key factor to be high-income. This is effective even if not all colleges employ this policy. (2) Financial support from grandparental generation may solidify the income class.
