Visitor Visa - B2

Today i had a B2 tourism/medical visa interview with wife and 5 yrs old daughter refused at US consulate in dubai, VO officer was a very young girl, People say that VO is very experienced and he can read your face micro expression but she didnt even seem to look towards us, she was constantly just typing in the computer.

Me Good morning Ma'am
VO good morning

Vo Pass passports please
Me gave

Vo why u wanna travel to america
Me basically tourism and to celebrate our wedding anniversary and hopefully white christmas
(answered as ppl suggested here to keep it simple, if vo needs further info then they will ask)

Vo where are u working
Me educational firm , its a school

Vo how many years
Me 7 years with this school as an accountant but with same management since i landed in UAE 10 yrs ago.

Vo so u r here since 10 yrs
Me yes Ma'am, ur right.

Vo whats your monthly income
Me 10k plus dirhams monthly

VO to my wife : where r u working Ma'am
i replied : she is a housewife

Vo she is also here from 10 yrs
Me: no we r married since 7 yrs and in dec we celebrate our 8th anniversary, so she is here ever since our marriage and my daughter from 5 yrs ever since she was born.

VO : did you travel before as a family in last 5 yrs..?
Me yes Ma'am we travelled to Georgia and offcourse UAE and Pakistan

Vo u have any other family member in UAE
Me yes my DAD, IN UAE since 35 plus yrs. and 65+ age

VO is he living with you
Me yes and working in the same firm.

Then she stopped questioning and just kept typing, i guess they have some super awesome computer, offcourse its american visa , they have may be access to all secret information of every person, i guess they have data for every person already through their sources.

At the end she replied that i am sorry sir under section 214(b) your visa is refused( Looking in computer screen, i guess reading the reason from computer)
Donno who is sitting on the other end of computer...?

When i asked whats the reason
she replied due to economic and family ties..!!

I replied that i am carrying bank st. please have a look,
she replied no need for that sir..

I feel its unfair because i was not even allowed to prove myself as financially strong with the heavy bundle of documents that i was cayying, she did not even ask for a simple paper.

I mentioned a hotel address on contact details in ds160 form and did mention if i know anybody in US, because people told me not to disclose your relatives in US,
Here people suggested me to apply with my family, it will make my case strong, did so but no use.
What should i do..? Apply alone cant get visa.. with family cant get visa..? what the hell we should do..? i am in UAE from 10 yrs which shows strong ties, daughter going to school, wife not working which shows i earn good to manage the cost of living in UAE.. father also in UAE, had with me healthy bank statement.

What could be the possible reason..? Any help or suggestion will be highly appreciated..??
And how i can improve my case..?

Did i select wrong visa category..? B2 tourism/medical..?
