What is Rat Race?

Robbert T. Kiyosaki defines "Rat Race" in "Rich Dad Poor Dad" as follows:

"If you look at the life of the average-educated, hard-working person, there is a similar path. The child is born and goes to school. The proud parents are excited because the child excels, gets fair to good grades, and is accepted into a college. The child graduates, maybe goes on to a graduate school and then does exactly as programmed: look for a safe, secure job or career. The child finds that job, maybe as a doctor or a lawyer, or joins the Army or works for the government. Generally the child begins to make money, credit cards start to arrive in mass, and the shopping begins, if it already hasn't.
Having money to burn, the child goes to places where other young people just like them hang out, and they meet people, they date, and sometimes they get married. Life is wonderful now, because today, both men and women work. Two incomes are bliss. They feel successful, their future is bright, and they decide to buy a house, a car, a television, take vacation and have children. The happy bundle arrives. The demand for cash is enormous. The happy couple decide that their careers are vitally important and begin to work harder, seeking promotions and raises. The raises come, and so does another child and the need for a bigger house. They work harder, become better employees, even more dedicated. They go back to school to get more specialized skills so they can earn more money. maybe they take a second job. Their incomes go up, but so does the tax brackets they're in and the real estate taxes on their new large home, and their Social Security taxes, and all the other taxes. They get their large paycheck and wonder where all the money went. They buy some mutual funds and buy groceries with their credit cards. The children reach 5 or 6 years of age, and the need to save for college increases as well as the need to save for their retirement.
That happy couple born 35 years ago, is now trapped in the Rat Race for the rest of their working days. They work for the owner of their company, for the government paying taxes, and for the bank paying off a mortgage and credit cards.
Then they advise their own children to 'study hard, get good grades, and find a safe job or a career'. They learn nothing about money, except from those who profit from their naivety, and work hard all their lives. The process repeats into another hard-working generation. This is the 'Rat Race'"
