Once upon a time Republican politicians invested in the infrastructure of our country. Lincoln was very instrumental in building the transcontinental railroad. Eisenhower was instrumental in building the interstate highway system. Both of these transportation systems transformed the United States, saved millions of dollars in transportation costs, and increased investment in other areas.
Now it seems the only "investment" Republican politicians want to make is in destruction, a so-called strong defense.
Everything else Republicans look upon as costs and taxes. Opportunity costs are not part of their accounting. They just don't see the costs that can be saved by investing in schools and colleges, in health care, and alternative energy. And they ignore the opportunities that these investments will create.
