SUMMERT

Actually, it happens more than you think. You are just not aware of it. See NYCruiser and my stories below.
 
@NYCruiser I got an even better story and one that is directly related the OP's and my wife's country.. the Dominican Republic. A country that I visit frequently and have family that are living there.
 
My wife has a half brother (her father had several kids outside of his marriage) who has a visitor visa. He has traveled here  many times. Never overstayed. He came to our house and ate dinner and we talked over beers. He is a business owner in Santo Domingo. He has what the Dominicans call a "wife". Now for those that don't understand the difference, in the DR, if a couple are together for a long time, live together and have kids, they call each other husband and wife even though it is not legal or official.
 
Anyway, my BIL has his Dominican wife that he has been with for years. They have 3 kids together. Two are grade school age and another that is about a year old. A few months ago my wife told me that her brother and his "wife" decided that they want the kids to go to school in the US because it is a better school system. She then told me how they are going to accomplish this. Apparently, my BIL arranged for a family friend to officially marry his "wife" and file a spouse visa for her(remember, they are not officially married so she can officially marry someone else). My BIL's "wife" will then move to the US so their kids can go to school. He has no plans on joining them. He will just visit them as often as possible for the time being.
 
My wife knows how I am about people who scam the system so you can imagine her reluctance for her to tell me their plan. She herself even says that it is unfortunate that they are doing it this way because since my wife has been involved with the immigration process, she constantly sees how people abuse the system and how it makes it bad for others. I shake my head in disappointment and my wife simply says, "Lo se, lo se" (I know, I know). Truth be told, even if my wife informs her brother of what they are doing is wrong (which I kind of get the feeling she has already), they are going to do it anyway. And to me, that is the biggest risk.
 
So @SUMMERT, I personally know of people from the DR (a beautiful country that I love) who separate from family to take advantage of US opportunities. There is nothing wrong with you not knowing anyone who does do it. But I can attest that is does happen more than you think. 
 
Also, many times when a person feels that the vetting process is unfair to the point where the system suspects a person is not sincere in there intentions are not looking at it from a proper perspective. The few bad people can indeed make things bad for the good. To give you an example, you don't lock your doors at night because of the millions of people who DON'T want to break into your house... you lock your doors for the small few who do.

Give me some examples of strong ties... cuz before applying I Read the checklist of supporting documents.
 
I’m Not trying to be rude with this but
now that checklist was a waste of time.
properties for them I can sell it or manage from outside.
for them I can left  behind my wife.
for them i can left behind my current job and studies, on the form I put the quantity of money I earn per month, i don’t think a people with neurons Working properly will leave an office for being washing dishes or picking garbage i don’t know the criteria of visa officer but seriously that young lady didn’t drink her coffee at the morning.
 
so what kind of ties can be strong for them ? 

A couple examples are:
1) Jobs that have been maintained for years and cannot just be left (i.e. companies don't higher middle level & up managers, highly skilled workers, etc. without verifying their work eligibility)
2) Travel history, especially to other similar "first world" countries.
3) The elderly without close US relatives tend not to be targets to uproot their life and live in the US.

You weren't refused because the consulate officer hadn't had her coffee that morning.  You were refused because per the statutes she is required to adhere to, she was not convinced of your intention to return to your country.
 
It is not black and white, or a case of "bring these documents and its a sure thing."  Its more nuanced, and based on the TOTALITY of how you present your case, both via the form and in person.
 
For example, someone else alluded to the fact that it could be considered unusual that you were not traveling with your SO.  I know you said that you have different vacation times, but if you are a business owner, wouldn't you have a little more leeway around that?  And in your culture, is it typical to travel for pleasure without your spouse?
 
Also, what was the final destination for your trip to the US, and did you have an itinerary with hotels booked?  Do you have family or friends here?
 
Any criminal convictions or arrests?  Are you male and young?
 
These are just some examples of what may be looked for on the DS-160 as they review applications before the interview.

Many countries have bureaucratic systems that are a complete joke but that doesn't mean there's nothing in that country worth visiting. I've heard that in Cambodia for example if you don't bribe the border officials you're not getting in but a vacation in Cambodia is certainly worth it

I am not trying to pick a fight.
 
They go through your visa application before interview. Irrespective of which visa. Our Cr1 was denied first and second time after 3 years they approved. we were as mad as anyone when our visa was denied 1st time. But when they approved second time, we understood the reason behind. They were testing our relationship. 
 
Coming back to NIV,  CO has learned a lot of lessons when people kind of forget to get back to their home country after the visa is expired.  Once bitten twice shy

You can not appeal, but you can reapply.
 
I am not sure what relevance you think those documents have.
