Does your country have insurance and whether is it useful to overcome your economic problems,
I see in some countries only people who have enough economics who have insurance
and those who are poor do not have insurance.
is this fair.
Insurance is indeed for the rich people and not for people who have a poor economy. And the purpose of insurance isn't make someone to get rich or become poor. Insurance is a place to save money or a place as your guarantee in old age. For example for your health care, with insurance you can treat your disease for free. Every month you will save money or spend money to the insurance you choose and there are several classes depending on your ability.
And I guess it's very rare for people who have poor economy to choose an insurance. For them to cover the cost of their daily lives will be arduous and they will not be able to pay every month.There is something wrong with your understanding of insurance, it will be good you read what insurence is and what the insurance function is.
