“Used to the conditions of a capitalistic environment, the average American takes it for granted that every year business makes something new and better accessible to him. Looking backward upon the years of his own life, he realizes that many implements that were totally unknown in the days of his youth and many others which at that time could be enjoyed only by a small minority are now standard equipment of almost every household. He is fully confident that this trend will prevail also in the future. He simply calls it the American way of life and does not give serious thought to the question of what made this continuous improvement in the supply of material goods possible.”
