I would have agreed with you if you had said that it is easier for a woman to make money than a man but saying that money buys happiness to majorly women is not actually true at all even though we know that women becomes more happy when they are given money or when they have their own money and every body generally is very happy when they have money but that doesn't mean that their money can buy them happiness, infact let me put it straight to you majority of women that has money are not really happy in their life as most of them fakes their life for people to believe and think that they are happy and living alright.
Women pretend a lot and cover their dark and painful side all the time but they are the ones that get emotional easily because of what they pass through in secret so saying that money buy happiness to the female gender is not true. If some successful women open the chapter of their lives you will feel so bad for them because they go through a lot even to get money because men literally work hard for their money but most female now are into prostitution and are using it as a way to earn a living and take care of themselves but do you think that this females are happy about the job they're doing just to make a living because if they consider the stress they go through it makes some of them get into emotional trauma and they feel so bad due to the fact that they are being slept by different men just to meet up life obligations so it's not easy for any of the genders at all because we all are going through some things that money cannot really afford for us. Some girls after making a lot of progress in life, they are not happy due to the nature they pass through to get to the top, they cry secretly and pretend everything is fine but deep down in them they are not really happy again when they keep reflecting on their past lives.
