The United States would be very different today if Kennedy had not been assassinated. If he had lived, Lyndon Johnson would probably never have been president. If Johnson had not been president, the Great Society programs would never have been launched. This would have meant that the welfare state would be much less extensive than it is now. Had the welfare state been less extensive, there would have been much less for conservatives to become angry about. This might have led to a situation in which the "Reagan Revolution" would never have come about. We would have not gone as far towards liberalism and so we would not have had such a big backlash towards conservatism. Our country would be much less politically polarized today.
