As usual Fargo is compilation of all fears and hopes of ordinary philister. Small guy with capitalist ideology hammered to his mind.

Main character are in the order of importance:

Gloria Burgle - implements idealistic dream of good government and authorities, but mixed with reality to make it better looking. Always care, but always did not do anything helpful, because it is late. She wanted to help, just bad guys (see below) did not let her.

Moe Dammick - this is another idealistic understanding of stupid government part, just wrong people. You just need to put right people...

Nikki Swango - minor role model for philister. Good logical criminal. But finally god must make her pay.

Ray Stussy - role model. Depicts someone who did not listen to mother and farther. Made wrong choices, did not work hard enough. Loves criminal - wrong thing.

Emmit Stussy - main role model. Guy did everything right, worked hard, highly moral. As life reward he is businessman, big, but not too big. With happy family.

V.M. Varga - all small bourgeoisie and petty bourgeoisie fears combined into one man. Comes as reckoning for trying to get money from wrong people. Capitalist raider. Money launderer. Do not care about finance books, just make fake ones. Criminal talents and criminals around. He do all this citing stupid pseudo communist phrases and with Stalin portrait. And constant Russians mentioning.

Otherwise it is just almost literal rephrase of children's tales. Work hard and with small luck( just a bit!) you will be good moral businessman living according to American dream, happy family and all good. But look... If you do not learn so hard, if you make errors... look at your drunk brother. He is zero. Bad guy making wrong decisions. But with luck (not a bit) and proper assistance he could also become rich... Sadly not much luck.
And be afraid, be very afraid. It is big sharks out where. If you make slight misstep they can come for you. And government won't be able to help. It'll try hard, very hard to help. But you know, rules, stupid people. Didn't work out fully. But if you stole few hundred million, we'll put it all on working people and just slightly hug you. Just do not kill guys who in love with criminals, you know. We won't save you here. Not our business.
