It is based on the principles of equality of opportunity, equitable distribution of wealth, and public responsibility for those unable to avail themselves of the minimal provisions for a good life.

TRADE: is the voluntary exchange of goods, services, or both. Trade is also called commerce or transaction. A mechanism that allows trade is called a market. The original form of trade was barter, the direct exchange of goods and services. Later one side of the barter were the metals, precious metals (poles, coins), bill, paper money. Modern traders instead generally negotiate through a medium of exchange, such as money.

HOUSEHOLD CONSUMPTION: is a common concept in economics, and gives rise to derived concepts such as consumer debt. Generally, consumption is defined by opposition to production. But the precise definition can vary because different schools of economists define production quite differently. According to some economists, only the final purchase of goods and services constitutes consumption, and every other commercial activity is some form of production. Other economists define consumption much more broadly, as the aggregate of all economic activity that does not entail the design, production and marketing of goods and services.

INTEREST RATE: is the price a borrower pays for the use of money they borrow from a lender, for instance a small company might borrow capital from a bank to buy new assets for their business, and the return a lender receives for deferring the use of funds, by lending it to the borrower. Interests rates are fundamental to a capitalist society.

TERTIARISATION: is an economic and social transformation that affects the most developed countries since the last phase of the industrial revolution (third industrial revolution).

PIPELINE: is the transportation of goods through a pipe. Most commonly, liquid and gases are sent, but pneumatic tubes that transport solid capsules using compressed air have also been used.
As for gases and liquids, any chemically stable substance can be sent through a pipeline. Therefore sewage, slurry, water, or even beer pipelines exist; but arguably the most valuable are those transporting fuels: oil (oleoduct), natura gas (gas grid) and biofuels.

FREIGHT: (or freight) is goods or produce transported, generally for commercial gain, by ship, aircraft, train, van or truck. In modern times, containers are used in most intermodal long-haul cargo transport.

GATT-WTO: the General Agreement on Tariffs and Trade (typically abbreviated GATT) was negotiated during the UN Conference on Trade and Employment and was the outcome of the failure of negotiating governments to create the International Trade Organization (ITO). GATT was formed in 1947 and lasted until 1994, when it was replaced by the World Trade Organization in 1995. The original GATT text (GATT 1947) is still in effect under the WTO framework, subject to the modifications of GATT 1994.
