Given this FAA justification for implementing NextGen ATC
privatization:

NextGen is not only necessary to accommodate increased levels of
commercial travel, but also to meet the growth in new types of air
travel that are taking the skies. We are expecting a surge in
traffic from a new generation aircraft called Very Light Jets
(VLJs). These high-performance jets are inexpensive and will be
able to land just about anywhere. Commercial Space is another new
market well under way that the must be accommodated in our air
transportation system.

I fail to see how VLJs specifically are an issue. Isn't it a
projected increase in the number of aircraft concurrently in the NAS
that is the perceived problem? Hell, if the thousands of BD-5s that
that charlatan-Jim had sold had actually been built, the NAS would
have reached grid lock conditions back in the '70s.

VLJs are just airplanes. What is the FAA afraid of, a massive
increase in Part 135 ops?
