The GMH is two stage but can't be set up with a two stage t-stat (second stage comes on after a preset time whether it's needed or not). The GMV is a better choice (ecm blower motor + t-stat controlled staging) - http://www.goodmanmfg.com/Home/Produ...8/Default.aspx
economic collapse is a certainty. debt based fiat currency monetary systems can never continue indefinitely because they require continuous creation of new debt to service the existing debt. in the absence of economical growth (which is always predicated on increased resource extraction rather than capital alone), this leads to massive inflation which destroys the currency.
your leaders can't fix this - they're corrupt and only exist to enrich themselves and their corporate friends.
