How about fair trade with any nation, socialist or not?
the grip of the financial sector could be curtailed. ......
.......Yes agreed, federalism between sovereign nations, autonomous regions, where appropriate and under control of peoples organizations and governance...
But curtailing the multitrillion dollare speculation community? This requires a whole other discussion...they dwarf any Nation`s economy, created by the elite Central banking system and their QE and zero or negative interest rates....this will require bankruptcies en masse...the big banks, the major corporations, most of whom are just speculative trading financial institutions anyway
