I am going to ignore the strange use off yoked, and associated negative Christian fundamentalist connotations...
But of we consider if it's better to have a relationship with someone with whom you are well matched in terms of circumstance, then yes, absolutely. You don't have to be identical, but balanced and reciprocal.
I have a modest income, own my own home, and don't have to worry about an unexpected bill or repair, and can buy anything I need, travel a lot, go to the theatre, can afford to eat out etc etc. It makes sense to be in a relationship with someone with a similar level of security and disposable income. I wouldn't want to be with someone who can never afford to go out, or travel, or lives in unstable housing as we wouldn't be able to lead the same lifestyle. Similarly, I wouldn't be able to afford to do the things someone who has a lot more disposable income than me would be able to do. I can't afford to spend £200 on a theatre ticket or a meal, or stay in luxury spa type hotels every time I go away.
I don't think level of education needs to be exactly the same, especially if you are at doctorate level, as that makes the dating pool small, but certainly matched in terms of general intelligence, moral values, and just engagement with the world.
Hobbies don't have to be identical. You don't have to both love cross-stitch, but it helps if generally they are aligned, e.g one with wanderlust and one who doesn't own a passport are unlikely to be compatible.
Fitness and lifestyle need to be compatible though. A toned size 10 lady with a pilates body or a ripped man who lifts weights at the gym is unlikely to be compatible with someone who is morbidly obese, doesn't exercise and eats take aways all the time. It's not about looks, it's about lifestyle.
