There seems to be no mainframe explanation for the PC world in which we're living.

I believe we can do much more to adapt to the structural changes in the global economy, get high-end manufacturing back here, set up clusters of economic activity where you have, among other things, continuous retraining of people well into their middle years so they never become irrelevant to the current job market.

Remember, Republican economic policies quadrupled the debt before I took office and doubled it after I left. We simply can't afford to double-down on trickle-down.

The good news is you can get a lot of information off the Internet for free and in a hurry. But I think the breaking up of the media, which is otherwise kind of healthy, has contributed to less actual reporting and a louder, more contentious, more divisive public discourse, highlighting conflict, sometimes falsely.

We should set a national goal of making computers and Internet access available for every American . . . we must help all Americans gain the skills they need to make the most of the connection.

I support lowering the level of legal immigration by a moderate amount at this time. Legal immigration reform must be based upon principles that are pro-family, pro-work, and pro-naturalization, retaining opportunities for family reunification as the levels are lowered. We must not let this issue become divisive in this country.

The real differences around the world today are not between Jews and Arabs; Protestants and Catholics; Muslims, Croats, and Serbs. The real differences are between those who embrace peace and those who would destroy it. Between those who look to the future and those who cling to the past. Between those who open their arms and those who are determined to clench their fists.
