You really don't know a whole lot about how the G20 operates, do you?
Meetings like this one are used to organize new trade agreements and reduce/eliminate tariffs, not regulate banks (which is by and large a domestic issue handled separately by each member of the G20).
The majority of protesters are antiglobalization nuts who think that the G20 is a "one world government" or don't understand that free trade is good.
Highly educated my ass. These protesters are violent thugs don't have "real concern". They're paranoid nutjobs who think that torching cars and inciting violence somehow gets their point across.
Hence the problem. You obviously don't know the G20:
The Group of Twenty Finance Ministers and Central Bank Governors (G-20, Group of Twenty) is a group of finance ministers and central bank governors from 20 economies: 19 countries plus the European Union. Their heads of government have also periodically conferred at summits since their initial meeting in 2008. Collectively, the G-20 economies comprise 85%[3] of global gross national product, 80% of world trade (including EU intra-trade) and two-thirds of the world population.[2]
The G-20 is a forum for cooperation and consultation on matters pertaining to the international financial system. It studies, reviews, and promotes discussion (among key industrial and emerging market countries) of policy issues pertaining to the promotion of international financial stability, and seeks to address issues that go beyond the responsibilities of any one organization. With the G-20 growing in stature since the 2008 Washington summit, its leaders announced on September 25, 2009, that the group will replace the G8 as the main economic council of wealthy nations

The Group of 20 leaders of the world's richest and emerging nations, holding a two-day summit in Toronto,
neared agreement on broad principles to halve their budget deficits within three years and toughen bank capital requirements, according to a draft communique obtained by Reuters.
But they are leaving room for each country to choose its own timetable.
China conceded that its yuan currency was a valid topic of discussion here, reversing its earlier opposition, as
the G20 tries to make good on a promise to iron out imbalances between export-rich countries, such as China, and indebted consumer nations including the United States.
The shift toward tailor-made solutions -- seen in the approach to budget deficits, bank reform and trade -- contrasts with the last three G20 summits where they linked arms to combat the worst global recession in decades.
The draft document shows countries will be given a choice whether to levy taxes on banks to recoup bailout costs -- Europe had pushed for a global tax -- and can phase in stricter bank capital rules to fit national needs.
If this doesn't look to you like a world financial government, just try substituting US states for nations. It operates very much like our Federal system.
While countries can theoretically buck the system, the enormous power of the G20 makes that very unlikely. Sort of like a US state deciding to buck Federal rules and give up Federal funds. Happens very rarely.
