I think our future is similar to the USSR. They simply went out of business and the power reverted back to the satellite countries. It appears to have made a difference what country you lived in. All survived but it was harder in some countries. I visited Mongolia after the fact, it was like the frontier, they had to reinvent everything and were discovering their past which as been repressed for 90 years.
Strange thing, I am actually encouraged by the possible demise of the USA because I don't think we can fix it.(but I am willing to be proven wrong)
Please, take heart - The USA has already died. It died many years ago.
what this is is the USA coming back.
