The thrust of President Carter's economic policy "is to divide our natural constituency and make it very difficult to organize people," Bert DeLeeuw, director of the Movement for Economic Justice, said last night before about 11 people at Phillips Brooks House.

DeLeeuw's speech on "Grass Roots Politics and Carter's Policies" is the third in a series of discussions on "Community Organizing."

DeLeeuw said lobbying Congressmen and demonstrations in Washington are not effective means to pressure Congress, because the corporate lobby in Washington is too powerful.

The time has come to revive civil disobedience tactics and disrupt the normal flow of business. DeLeeuw said, adding that corporations and not the government must be the main target of these tactics.
