Savings is must for emergency purpose. Ideally, $1000 savings for a family is enough so that if somrthing happen to a family member (assuming that it's just a minor accident), they are capable of paying the hospital bill. The rest of someone's spare money can be put on investment then for a long term profit purpose. Although it gives profit, it's not very convenient to use it for emergency purpose.
yes, savings will indeed be very useful for emergency purposes. but, as business people, we cannot just save the assets we have. if we want to grow, we need to take risks and make investments that have great potential. it is indeed risky, because that we can do it by storing some assets. the point of this is, we need to insert some of our assets to be saved because we never know the sudden needs that we will use in the future. but, we also need to do other business, therefore use 30% of assets to be saved, and 70% to build a business.
