The Washington State Constitution says:

ARTICLE IX
EDUCATION
SECTION 1 PREAMBLE. It is the paramount duty of the state to make ample provision for the education of all children residing within its borders, without distinction or preference on account of race, color, caste, or sex.

SECTION 2 PUBLIC SCHOOL SYSTEM. The legislature shall provide for a general and uniform system of public schools. The public school system shall include common schools, and such high schools, normal schools, and technical schools as may hereafter be established. But the entire revenue derived from the common school fund and the state tax for common schools shall be exclusively applied to the support of the common schools.

The paramount duty is NOT to give tax breaks to rich people and corporations that pay a lower tax rate than the middle class & the poor.
