For your information and reference, I tell you a real story here:
I have  friends who are a couples, classmates in same universities in China, majoring in medicine both, came to  the States about 20 years ago and have lived there in the USA till now.
The couples are all Doctors with very high incomes, over 500k annually that time 10 years ago,  and possibly 1 million now , living in a huge house with 8 bedrooms, over 6000 sft. 
One day I got a call from them and they told me that all their 4 parents living with them together to look after their 3 kids and doing house works in home. They were so excited and  happy that time, seeming  to live in heaven!
After a few months, I got another call from this couples in the voice of cry, told me that they just came back from hell.
Now you guys must know the results of the story, and do not wate your time to let me continue, right ?
Okay, let us ask that
 
Is this couples rich?
Yes.
Do  they have a good codition and facilities to live?
Yes.
Are the husband or wife well educated?
Yes, both of them have Phd. degrees.
The results is that there WERE fights every DAY,  between the parents of two SIDES, between the parents-in-law with the son-in-law, and/or daughter-in-law, ..... balabala.
Finally, all the parents went back to China.
Fortunately, the marriges was saved at last.
I guss, if you don't mind that 
This is the best result you can get !
No matter how nice you are, and or how lucky you are !
