Slavery &"Power from the People"

I received the "Power from the People: Summary Report July 2012" the other day following the announcement of the reduction of Feed-In-Tariffs (FiT's)to the wholesale price of 8-10c.
It makes interesting reading particularly when you compare the Choice Magazine article on Payback times for purchased Solar PV systems (27 Sep 2011).
As a personal Choice Magazine subscriber and a librarian I have hoped that Choice will revisit this article regularly to see what changes over time.
I would particularly like to see this soon, factoring in more recent cuts to PV system costs,  the reduction in the various incentives (REC's, STA's) and the cut-back of FiT's, and the increase in electricity prices from the Carbon Tax. (By the way an interesting article in The Financial Review (Sat 29 Sept 2012) on the various increases over each state of Australia)
This highlights one of the pitfalls of government intervention - always changing the rules as the money goes out of the budget. Of course, one of the reasons for government intervention is to encourage innovation, which reminds me of the recent Science Show.
As Lord John Kreb's (on Radio National's Science Show 15 September 2012) said: " Yes, one argument would be this is not the time to introduce more regulations when the economy is in a poor state, business is saying we need deregulation to grow faster to get back on our feet. The counter view is that regulation can drive innovation."
and " this reminds me of what happened when legislation came forward for the abolition of slavery. Business said, 'But we need slaves, if you abolish slavery you'll hamstring British industry, you'll destroy our competitiveness.' What happened was when slavery was abolished, innovation kicked in and jobs that were done by human hands in slavery were done by machines."

So various governments and business beware - innovate and look after your people, encourage appropriate payback times for small investors and they will look after their businesses.
