But if they just work smarter with what they have the POLITICIAN cannot
boast: "I'm getting the latest and greatest stuff for you, planning ahead
for you, and new business will want to come HERE instead of THERE!!
Our PIPE is gonna be a big pipe, ten times bigger pipe than our neighbors
dinky little pipe. It will be a huge pipe!! Guess who will pay for that big
new pipe? THEY will pay to build it!
While your explanation about compression and timing makes sense to most
people on this list, BIG pipe is an easier and sexier sell for the
Explain and tout big pipe vs image compression and smarter utilization of
we have. Which is better and easier for a Politician to understand and
explain - to sell.
Maybe it's a Human, Political Problem Jim!
