During this season of “prosperity,” what changes does the family make?

From the text:

So there passed another summer. It was a summer of prosperity, all over the country, and the country ate generously of packing house products, and there was plenty of work for all the family, in spite of the packers' efforts to keep a superfluity of labor. They were again able to pay their debts and to begin to save a little sum; but there were one or two sacrifices they considered too heavy to be made for long—it was too bad that the boys should have to sell papers at their age.
