In a survey, up to 2 / 3 of the respondents believed that the most important factor affecting the sense of security was the level of income. Analyzing the sense of security of people with different incomes, it was found that the sense of security of people with a monthly income of 3000 ~ 6000 yuan was significantly lower than that of people with a monthly income of 6000 ~ 8000 yuan. 
Many people believe that a stable income is more likely to give people a sense of security than more income
 the lower the income, the lower the sense of security.
