ELI5: What can high-profile law firms do to win cases that smaller law firms can't?

In other words, what's the difference between highly-paid attorneys and lower-paid attorneys?

Larger top-tier/Magic Circle law firms pay their employed solicitors very well, and they're very large organisations. This gives it three main advantages. 

First, they have more people that they can put on the project (which achieves certain economies of scale/cost). 

Second, the people they have are likely the best lawyers around, because they are given more money for working with the big firms than the little firms. 

Third, and perhaps most importantly, the size of the firms allows the lawyers within to become more specialised. Many big legal matters are complicated, and your local attorney will have to know about things like contracts for goods or services or land, conveyancing, family law, basic criminal law, etc. That means your local attorney will necessarily have less experience and knowledge than a specialist in any one technical area because they won't have the time to devote to other things, like corporate insolvency, or intellectual property. They'll only know the basics well, where a lawyer from a big firm can have specialist knowledge of the area of law that's relevant.
