globally, you d have low oil price it goes down, used to be it was great for america because we imported oil but now we have all this domestic production. could you see real downturn in that? i would argue be ready, i believe the three percent growth more or less they saw in 2008 in my opinion that was sustainable. without trade. i agree with you. we were on a path for two, three or four years. and now we re looking at this implies a level of sophistication that is inaccurate but were using 3.8 percent gdp growth next year. i think i would say whether it s agricultural commodities or other commodities, energy has impact we are already seeing growth, you re ready seen that more of two and half percent were little less.
