This may be a big dramatic but when the Roman empire fell it took centuries

Some people would have noticed the trend but like an avalanche it's something that cannot be stopped

It's like people in East Asia not wanting children it's a social choice

Also when people give people free money it leads to their financial situations worsening and they don't spend money on education

Or spend time with their family the average human being is pretty lazy
