Why does wealth cause some people to treat others differently

Sometime I can't believe how people treat each other.  I'm hearing and reading about stories of people saying they will not give their wife her stimulus check of $1,200 because she will go spend it all. Instead she will get a few hundred. 

Whats is wrong with people.  Why do spouses treat each other like kindergartens. Why does the husband think he can mange their money better then his wife? Why does she have to have an allowance?

The problem is that she doesn't know or isn't allowed to know their financial picture. It is true in most couple one person takes on this pardon and the other either doesn't care/not interested or is excluded.

I work continuously to talk to my wife about our finances. I have varying degrees of success on this.  There are times she asking if she can I buy this $$$ thing or pay off this other bill.  I then got look at MINT and review our finances and tell her not this month or sometimes I give bad responses. One of my more famous responses "sure go ahead we have tons of money." What I really meant was based on how much we normally have in our checking and bills coming due we have an extra buffer before the next paycheck without transferring money out of savings.  Easy to see why says that can cause problems.

I have friend who are married and the keep their finances completely separate. Not sure how I feel about this, seem like it will causes more problems then it fixes. The big issue is people don't want to face the facts on how much they spend and what they spend there money on.  Either they don't want to do the work or don't care and feel like they work hard they deserve to spend their money. 

I think this sentiment is the reason why some people feel like they own their families money and only give their spouse an allowance.  Its like a marriage allowance for marring the person that they feel they are doing the right thing because their spouse don't have any self control like they do. 

If everyone has the same goals and talk through these goals having everyone stick to a budget is much easier.  Goals are defined

1. What you want to achieve   example (pay for college $150,000)
   
2. When you want to achieve it   example (18 years from now)
   
3. How are you going to achieve it    example (save $695 a month) or $160 a week or $22 a day (a price of a coffee at $tarbuck$)
