Those of you pushing for a gas tax might not have thought all the way through it. The inflation that will result from increasing tax on gas will be rather substantial. A .25 increase will filter through almost immediately as trucking and distribution companies take large price increases that they push down to producers, manufacturers and distributors of all types of goods and raw materials. These companies will immediately take price increases on retailers who, in turn, push it down to consumers as many of them operate on razor thin margins as it is, and capacity in the trucking industry is already massively short on drivers and equipment (due to the pushing of electronic logs requirements).
The 350,000 independent truck driver contractors out there will immediately get hit with this increase in cost and will probably not be able to recover the pricing as easily as larger businesses (or as quickly). A good portion of them will likely fold.
