Still, other radical reform proposals emphasise monetary, tax and capital budget reform which empowers government to direct the economy toward sustainable solutions which are not possible if government spending can only be financed with more government debt from the private banking system. In particular, a number of monetary reformers, such as Michael Rowbotham, Stephen Zarlenga and Ellen Brown, support the restriction or banning of fractional-reserve banking (characterizing it as an illegitimate banking practice akin to embezzlement) and advocate the replacement of fractional-reserve banking with government-issued debt-free fiat currency issued directly from the Treasury rather than from the quasi-government Federal Reserve. Austrian commentator Gary North has sharply criticized these views in his writings.
