I have read that the G20 members want to have the US enforce the trading regulations in their (advertised but yet to be realized ) free markets.
The filth in new jerk and their paid for puppet politico's don't want enforcement. They will change their mind when the rest of the world reduces their investment in all things USA. The reduced investment in US stock and bond markets will put a ring through their noses and they will make SOME efforts to demonstrate rule enforcement and possibly market transparency.
We will get some, but onlt that the filth needs to encourage global investment in the US markets. They need $ investments to keep their parasitic ponzi scheme going.
