Kama Karl Polanyi anavyosema, ubepari ni hali isiyo ya kawaida - kwani ni mfumo ambao mahusiano ya kijamii yanaamuliwa na mahusiano ya kiuchumi. Hii ni tofauti na mifumo ya zamani ambapo mwingiliano wa kiuchumi ulifuata kutokana na mahusiano ya kijamii20. Ubepari unakabiliwa na matatizo makubwa zaidi ya kidhana:

As Karl Polanyi argues, capitalism is an anomaly - for it is a system, where social relations are determined by economic relations. This is unlike in previous systems where economic interactions follow from social relations20. Capitalism suffers from bigger conceptual problems:

1. Kuchanganya mahitaji na njia za kuyatimiza.

1. Mixing needs and their means of satisfaction.

2. Mahitaji ni ya kimwili pekee.

2. Needs are only materialistic.

3. Bidhaa na huduma hazihusiani na muundo wa jamii.

3. Commodities and services are not related to the structure of the society.
