NCR is nothing like far right socialism, they are by all means 18~19th century US and mostly run by businessmen; they also have expanding across the continent (but backwards).
NCR only does a passable job for for keeping raiders away, even back in California. As for how much NCR care for its people, you can ask your senator.
Maybe you are right , but the way i see it :
- President Kimball has no opposition within the NCR , he is some sort of dictator , besides i didn't hear about elections or citizen voting
- NCR doesn't care about individual freedoms , displace people from their lands , prevent business to function properly as they over-tax the merchants who are left with barely nothing to survive , hence why some merchants prefer to trade in the Legion territory
- NCR emblem is the red star , NCR integrates people through the military almost exclusively , people who aren't part of them are expandables , when you are not NCR , you have no rights and can lose your property ( NCR doesn't repect private property unless it is NCR"s ) or business
- Instead of allying with pro-business Mr House , NCR wants to "nationalise" Vegas , to acquire it for its own needs to fund its expansion/war effort , NCR doesn' t care one bit about the people of Freeside
Stuffs like that makes me tend to think they are not far from an authoritarian regime similar to communist regimes ( corruption , regime that has his hand on all the wealth of the country , the people kept poor , free market and business discouraged etc ) , i've seen some propaganda signs at Mc Carran that says "NCR brings democracy" , but they are deceiving the people really , there is nothing democratic in the way they behave in the Mojave from what i've seen , but ok i may be wrong
