Some aspects of a cashless society would not be very palatable to the elite, I think.
If they removed cash, that would force those who hire illegal aliens to pay the going wage, along with benefits and taxes. That would remove their entire incentive for hiring illegals over Americans. It would also impeded the functions of those businesses that profit from slave labor (i.e. human trafficking). As a result, the elitist push to open the borders to even more illegal aliens (i.e. Democrat voters) would be severely restricted.
As long as the elites benefit by cash, it will not disappear.
You have a point, but once the globalists have us where they want us, it won’t matter anymore. Illegals, terrorism, racial/gender division are all a ploy to get Americans to accept - even desire - the New World Order.
Power, wealth, total control of the people, depopulation is the end game for these people.
