East Asians' definition of "family guy" is those who devote himself completely into work for his family. Its their role to put total focus on work in order to support their family.
That's why they have way longer working hours, more overtime without pay, and less outgoing in general. They do it for their family.
Since East Asia turned from an agricultural country to an industrial country, they begin to focus more on the quality of their children rather than quantity of their children.Thus, their living cost rised dramatically.
In East Asia, its the father's responsibility to earn enough money for their children to get into college/university. That's why their children have to be obedient and be filial to them at all times because their father will pave the way for their children by slaving themselves. They don't even expected to retire early like western counterpart, they were expected to work to his end of life in order to earn enough savings for his future generation.
When they say the living costs is too high to start a family, don't forget they have included higher education expenses for their children in their bill. Its impossible to have more children without considering their education cost in their bill.
That's why its very hard to find a date if you don't have a stable, high-income job in East Asia. If you don't have your own property likes house, car and etc, that's means your income wasn't stable enough to start a family.
With all these pressure, its getting more common for East Asian men to not marry at all because they have to basically pay for everything but for himself.
