Напишите пожалуйста грамотный и понятный перевод

If a person can do what he wishes with his own property, time, and energy, then economists say that he is "economically free". In all communities, of course, limits are imposed upon the personal freedom of their citizens and these limits are in some cases very complex but in others relatively simple. All individuals are required to conform to the laws made by their governments. Complete economic freedom of action can create great difficulties, because the freedoms exercised by various individuals often conflict. If citizens were completely free, some landowners might build factories in unsuitable places, while some factory-owners might make their employees work too long each day. If they were completely free, workers might stop work when they got their first pay, and come back only when they needed more money. Such economic anarchy could cause instability (unemployment; loss of production etc.) in the whole economy of a country. Laws related to economic conditions are sometimes concerned with contracts between employers and employees. Sometimes they are concerned with workers' health, wages and pensions, and sometimes with the location of places of work. Sometimes they protect the interests principally of the workers, while at other times they may be beneficial towards the employers. The government policy towards both employees and employers will depend very much upon the political and economic ideology adopted by the government, and may be biased towards employers and capital on the one hand, or workers and the problems of labour on the other hand.
