justice between men and women?

Aoa. I want to ask a question that has been disturbing for a while now. I hope to get help from you soon. Islam allows men to have four wives and also keep the slave women. While the woman is to be loyal to her husband soleley. Is it fair towards a wife? She has to tolerate her husband being with many other women but has to be with him only? Justice? Then she has to please her husband whatever or however the husband may be. His displeasure could cause her to be in hell. But if he doesn`t fulfill all the wife`s rights, there`s simply no threat or punishment for men. They are just given a relaxed hand to treat their wives any way they want, and the wife has to be obedient no matter what. Even if she tolerated all this with patience solely for the reward of the hereafter, she again finds out that shell has to be with her husband in Jannah and not only him but his hoorein as well. Is it fair? Fine I know there will be no feelings of jealousy then but about now? Allah has given us feelings now in this world. How a woman will feel to know that she has to be loyal to a person who can have as many slave women to enjoy in this world and will have hoors in hereafter? A woman merely demands love and loyalty from a relatioship, why has Allah ignored her feelings just to fulfil a man`s wishes.? Does Islam favours men? And then a woman is made all dependent on man. She isn't allowed to have a second of freedom without husband`s permission. She like a caged bird in Islam. All the time spent in pleasing a husband who can be pleased by many women. And if she asks for divorce she`ll end up in hell. But a husband can throw her off whenever he wants and only the wife would be blamed for displeasing her husband. They are always dependent on men for finance can't even build up their self esteem by working without a husband`s permission. What are women given in this world and the hereafter? Is it fair? Please don't compare Islamic status with pure Islamic status of women. Islam considers the pleasures of men only. In all Quranic verses and sunnah, the word men is used. Please clarify in detail.
