Personal retirement accounts should be familiar to federal employees, because you already have something similar, called the Thrift Savings Plan, which lets workers deposit a portion of their paychecks into any of five different broadly-based investment funds. It's time to extend the same security, and choice, and ownership to young Americans. Our second great responsibility to our children and grandchildren is to honor and to pass along the values that sustain a free society. So many of my generation, after a long journey, have come home to family and faith, and are determined to bring up responsible, moral children. Government is not the source of these values, but government should never undermine them. Because marriage is a sacred institution and the foundation of society, it should not be re-defined by activist judges. For the good of families, children, and society, I support a constitutional amendment to protect the institution of marriage. Because a society is measured by how it treats the weak and vulnerable, we must strive to build a culture of life. Medical research can help us reach that goal, by developing treatments and cures that save lives and help people overcome disabilities -- and I thank the Congress for doubling the funding of the National Institutes of Health. To build a culture of life, we must also ensure that scientific advances always serve human dignity, not take advantage of some lives for the benefit of others. We should all be able to agree -- -- we should all be able to agree on some clear standards. I will work with Congress to ensure that human embryos are not created for experimentation or grown for body parts, and that human life is never bought and sold as a commodity. America will continue to lead the world in medical research that is ambitious, aggressive, and always ethical. Because courts must always deliver impartial justice, judges have a duty to faithfully interpret the law, not legislate from the bench. As President, I have a constitutional responsibility to nominate men and women who understand the role of courts in our democracy, and are well-qualified to serve on the bench -- and I have done so. The Constitution also gives the Senate a responsibility: Every judicial nominee deserves an up or down vote.
