All of the scholars are in agreement that marriage is something recommended (mustahabb) and called for in Islam. Some took it to the level of obligatory (waajib) for those with the ability based on the Prophet's (sas) statement:

"Whoever has the ability should marry for it is better in lowering the gaze and guarding one's chastity. Whoever is not able, let him fast for it is for him a restraint." (Al-Bukhari)
Without doubt, marriage is part of the social agenda of Islam and the objective it to maximize marriage and to combat "singlehood" as much as possible. This means that if marriage begins decreasing for whatever reason such as exhorbitant dowries, economic injustice, etc. then these evils must be combatted in defense of marriage. If polygamy is neglected and not done sufficiently, this will create a number of single women and a situation which requires social effort to correct. Likewise, if polygamy is done to excess by some individuals, it will produce an excess of single men another situation which must be corrected. The raising of children must be done in such a way which promotes marriage and raises both men and women knowledgeable of their roles and duties within the family. All of this can be found in Allah's command to the Muslims as a whole to maximize marriage among us:

{Mothers nurse their babies two whole years for those who wish to complete their nursing. Upon the one for whom the baby was born is her food and her clothing in equitable and proper terms. No soul will be emburdened beyond its ability. No mother may be harmed on account of her child nor any father by his child and the heir is chargeable in the same way. If the two [parents] decide on weaning by mutual agreement and consultation, there is no blame on them. And if you decide on a wet-nurse for your children, there is no blame on you provided you pay what you offered equitably and properly. And fear Allah and know that Allah sees well all that you do.} Al-Baqarah:233

{O you who believe, let not your wealth nor your children divert you from the remembrance of Allah. And whoever does that are indeed those in loss.} Al-Munafiqoon:9
We have now summarized the possible harms and benefits in marriage. So, the ruling regarding marriage for each and every individual - as to which is better for him, marriage or staying single - is measured against these harms and benefits. Each seeker of Allah should measure himself against these factors and conditions. If none of the harmful issues are present and the benefits are all apparent such that he possesses [sufficient] wealth and good character, is a young person with a need for companionship, then there is no doubt that marriage is prefereable and must be sought. On the other hand, if many of the harms are suspected or feared and not all the benefits will occur in any case, then staying single may be preferable for a particular individual.
