Should be a serious economic crises on the way, perhaps within 6 months to a year. Regardless of who became President in the USA, Trump or Hillary, the coming crash was pretty much locked in. P/E ratio hasn't been so skewed since .com crash or just before great depression times.
i think there nothing such to happen in near future they have a very strong and stable economic condition as compare to other countries therefore i do not think that any such think can be possible in near future.
Definitely, but still, there's nothing impossible in this world, trump can just make a regulation which is really controversial and could trigger internal problem among states that may turn the current condition of this country into a chaos. Only if trump is able to let his regulation through complicated things that can make it as the official regulation.
