If I'm understanding this correctly, every person, except the Nobility, was required to wear a hat on Sundays and Holidays. You might not be able to afford to feed your family, but you must buy a cap from an official capper tradesman. In the interest of keeping those makers in business. Even though they were no longer "fashionable". Was this an early version of "financial stimulus"?
"Historical significance: In England, the manufacture of caps was of sufficient importance to merit control by Act of Parliament from 1488 onwards. The 'Cappers Act' of 1571 stated that every person above the age of six years (excepting 'Maids, ladies, gentlewomen, noble personages, and every Lord, knight and gentleman of twenty marks land') residing in any of the cities, towns, villages or hamlets of England, shall wear on Sundays and holidays (except when travelling), 'a cap of wool, thicked and dressed in England, made within this realm, and only dressed and finished by some of the trade of cappers, upon pain to forfeit for every day of not wearing 3s. 4d.'. This act was intended to keep domestic production alive, as caps were outmoded by this date and there was a danger that a fall in demand for them would have a detrimental effect on the makers.
