I dont know abt u bhai sahib but usually when rishta's are arranged things like education, career all come into play. It doesnt matter if its love or arranged, all parents are equally concerned abt the wellbeing of their children and therefore alot of things are discussed during the process.
It looks like your wife is actually typically frustrated with the way things are going - you dont have a degree, as opposed to the fact that she does, makes a good living, supports her family and what not. I don't know why people think that if they are 'qaabil' and have good work ethics they can get any job. Living in a foreign country is hard.. its not easy especially if you cant make a living on your own. She, being your wife is supporting you and thats an amazing thing, but it seems like you do need to try a little harder. Try and take some courses at a local community college, maybe talk to a counsellor at a high school and see what your options are. Do u mind me asking how much schooling you had completed prior to coming here?
If you are planning on starting a business maybe nows the time to actually do it. Sit down with her and talk to her, and stop telling everything to your family. Your a married man, your responsibility is to your wife. I dont get why your family needs to know everything that you do or say or fight about. Its just going to make things harder on you and on her as she might feel judged upon. Also, that whole issue about what I like to eat menu thingy, why cudnt you have sat down with her and said that I feel like eating this today, could you make it? I'm sure she would love to and if she didnt have the time she would certainly keep it in mind to cook it some other day. My mom alwayz used to say one thing: Love is not going to put food on the table; education is, so if you dont have one dont expect the other to pay for your mistakes.
Also, as far as the comparing part goes, sometimes, when u dnt have something others do, it feels like your being compared whereas to the other person it might just be a comment. Unless she literally comes up2 you and tells u that u have done nothing and this person is doing this, has this many houses etc etc, dont care.
I think if you handle the situation properly things might work out. Try and see your options as far as education goes, and talk to your wife abt things, rather than your mother and sister. They are not the ones in this relationship and they are not living with u at the moment, she is though.
