Well, let's get past the rhetoric and look at what the nation needs.
First, we need to rebuild our failing infrastructure. Our grid is an antique, and our highways are decaying at an alarming rate from lack of basic maintenance. We need more energy, and to become far more efficient in our use of energy.
Second, we need to get into high tech manufacturing in a big way. Not just computers, but solar power, wind generators, efficient autos, efficient appliances, all the areas that China is making a major push in.
Third, we need to educate our workforce. Even South Korea is turning out more engineers than the US is.
Now, what are the candidates approaches on each of these issues. Romney, and the 'Conservatives' that support him would even defund k-12 schools, and regard higher education as something only the very wealthy should have access to. They state otherwise, but their efforts to defund the public school system speaks far louder than words.
The support and development of high tech manufacturing is going to have inevitable failures. For every Ford, there were dozens of startups that only made a few to a few thousand autos and then went broke. Someone with a good idea sets up a manufacturing line, and someone with a better idea at less cost undercuts him and puts the company out of bussiness. But the 'Conservatives' would shut down the whole industry because of the one failure. As far as government support of fledgling new tech goes, look at what other nations are doing and have done. We fail to compete, we lose.
Businesses cannot thrive without basic infrastructure. Transportation, power, water, and waste disposal. Yet the 'Conservatives' oppose anything that might give us a stronger more resilent grid, oppose rebuilding our Interstate road system, oppose the federal government involvement in such things as water and waste systems, even though there are states whose financial future is looking dim for the lack of water.
We can go forward, toward a future where we are competative with all the other high tech nations, or we can stagnate as the 'Conservatives' would have us do, and become a third world nation.
