Tools would have to be made, food would have to be gathered or hunted, local plants would have to be tested for medical use, clothing would have to be created from whatever is useful, and fire building would become a necessity. All of these actions would require talent and inventiveness-which all humans have the ability to develop and expand. It does not take an Einstein to develop the basic knowledge needed to survive. Nor to organize a society to provide care to those who need it, especially the children. But unfortunately, we live in a system that values people the least and private property and profits the most.
Capitalism needs profits above all else.
If a profit cannot be made, then nothing has a right to exist. That's why the capitalist class is working overtime to destroy public schools and turn them into profitable enterprises, starting with the voucher system. The voucher system promises better schooling, but like Firestone tires they will explode once our public schools are in private hands. Then it will be the parents who will be bilked out of every penny in order to have schooling for their children. Just as a college education costs thousands of dollars today, so will education in the private elementary and middle schools.
