There are enough burdens, concerns, and troubles that occur in the present without worrying about those that will or may occur in the future. Don't waste your time and energy worrying about what might go wrong. Just focus on every step of the project as it occurs. Sufficient unto the day is the evil thereof. In trying to legislate for problems down the line, many of which may never even come to pass, the government is failing those who need help right now. This protest march is thus being held to remind them that sufficient unto the day is the evil thereof.
