2 and 3 are net negatives, giving too much power to the leader of the country...bread and circuses in their prime example. 4 is debatable, but in general - bad, money laundering is what the BigBrother decides it is.
The lowliest slave could hope to escape to the North and be free, if we talk about US style slavery.
Or have their owner grant them freedom if we talk ancient Greece, Rome, etc...here not only the owner BUT the state has to agree as well.
If all the payments go trough the BB - you cannot pay for anything
Now even if I'm the lowest of the low I can scrape by a few coins and buy myself a loaf.
The govcoins are going to be the modern day techno-slavery. You would not be able to buy a loaf of bread without Big Brothers.
It is sickening that people say how good of an idea it is. SHAME ON YOU!
