So you pay for the dredging, the shorline maintainence, and in many
cases the gazillion dollars for the dam and land costs that created that
lake??

Public funding of small city/county airport by local govt especially
makes sense because of the economic activity it generates. its a simple
$- in $$$- out equation.



The economic benefit studies are bogus. They simply tally the payrolls,
then add a multiplier. If the airport ceased to exist entirely, the
discretionary entertainment $$ would be spent elsewhere and have some
economic value as well.

I don't know of any govt. dredging for private marinas (none that I have
ever visited), only for public ports that import/export cargo ships use.
I never really looked into it, but if public $$ go to a private marina, I
would definitely be opposed on principal: Why should you pay for what I
use if it provides no benefit to society??

Dams: built to generate power, primarily. Low cost hydro power. Not for
boaters.

Shoreline maintenance: I agree with that. But it is mostly done to
protect housing built (stupidly, I think) along the coastline. Homeowners
should bear that risk (or pay an insurer to bear the risk), not taxpayers.
(Unless it supports a military base or Cape Canaveral, or something like
that.)
