<human>: Answer by taking a quote from the following article:

Robert Owen (; 14 May 1771 - 17 November 1858) was a Welsh textile manufacturer, philanthropic social reformer, and one of the founders of utopian socialism and the cooperative movement. Owen is best known for his efforts to improve the working conditions of his factory workers and his promotion of experimental socialistic communities.

Owen embraced socialism in 1817, a turning point in his life, and began making specific efforts to implement what he described as his "New View of Society." Owen outlined his position in a report to the committee of the House of Commons regarding the country's Poor Laws. In addition, when misery and trade stagnation after the Napoleonic Wars were capturing the attention of the country, the British government invited Owen to offer his advice on what could be done to alleviate the industrial concerns. Although Owen attributed the immediate causes of misery to the wars, he also argued that the underlying cause of distress was the competition of human labour with machinery and recommended the establishment of self-sufficient communities.  Owen proposed that communities of about 1,200 people should be settled on land from 1,000 to 1,500 acres (4 to 6 km2), with all of them living in one large building that had a public kitchen and dining halls. (The size of his proposed community is likely to have been influenced by the size of the village of New Lanark.) Owen also recommended that each family should have its own private apartments and the responsibility for the care of their children until they reached the age of three. Thereafter, children would be raised by the community-at-large, but their parents would have access to them at mealtimes and on other occasions. Owen further suggested that these socialistic communities might be established by individuals, parishes, counties, or other governmental units. In every case there would be effective supervision by qualified persons. The work and the enjoyment of its results should be experienced communally. Owen believed that his idea would be the best form for the re-organisation of society in general. He called his vision for a socialistic utopia the "New Moral World."  Owen's utopian model changed little during his lifetime. His fully developed model considered an association of 500 to 3,000 people as the optimum number for a good working community. While mainly agricultural, it would possess the best machinery, offer a variety of employment, and, as far as possible, be self-contained. Owen further explained that as the number of these communities increased, "unions of them federatively united shall be formed in circle of tens, hundreds and thousands" linked in a common interest.
