He never said that. He did say this, which is far better than that short false 'death bed' quote that anyone who isin opposition to your view of the fallen republic would use against you:

President Andrew Jackson’s final warning to the people of the united States:

The paper-money system and its natural associations –monopoly and exclusive privileges– have already struck their roots too deep in the soil, and it will require all your efforts to check its further growth and to eradicate the evil. The men who profit by the abuses and desire to perpetuate them will continue to besiege the halls of legislation in the General Government as well as in the States, and will seek by every artifice to mislead and deceive the public servants. It is to yourselves that you must look for safety and the means of guarding and perpetuating your free institutions. In your hands is rightfully placed the sovereignty of the country, and to you everyone placed in authority is ultimately responsible. It is always in your power to see that the wishes of the people are carried into faithful execution, and their will, when once made known, must sooner or later be obeyed; and while the people remain, as I trust they ever will, uncorrupted and incorruptible, and continue watchful and jealous of their rights, the Government is safe, and the cause of freedom will continue to triumph over all its enemies.

But it will require steady and persevering exertions on your part to rid yourselves of the iniquities and mischiefs of the paper system and to check the spirit of monopoly and other abuses which have sprung up with it, and of which it is the main support. So many interests are united to resist all reform on this subject that you must not hope the conflict will be a short one nor success easy. My humble efforts have not been spared during my administration of the Government to restore the constitutional currency of gold and silver, and something, I trust, has been done toward the accomplishment of this most desirable object; but enough yet remains to require all your energy and perseverance. The power, however, is in your hands, and the remedy must and will be applied if you determine upon it.”

President Jackson called the attention of the people to the necessity of being vigilant, year after year; the necessity of constantly educating themselves –and not waiting for others, for cheer-leaders and heroes, to do the informing and the vigilance for them; to do the preserving their rights for them.
