Agreed, so long as there are politicians and commercial money involved in a public proposition there is room for concern.
IMO, no such proposition should reach the formal stage until an apolitical group of experts, economists, etc. demonstrate a financial gain for the taxpayers.
The Film Act discussed in this thread clearly appears at midpoint of its life to date to have been just the opposite.
Spot on! (I did feel compelled to add the unions to that...:)
