Nearly all major commercial contracts have an arbitration clause, so it's true that those conflicts are rarely litigated. "Disputes" are expected, but they go to arbitration. That doesn't at all mean that any relationships are ruined.

There is a whole industry of arbitrators for hire. They are usually specialised in some field of business, so they don't need bringing up to speed. And they're all experienced lawyers. The work is nearly all paperwork - submissions, affidavits, disclosures. There is rarely a face-to-face hearing. It's more like doing accounts-receivable than sueing someone's ass.

"Just business", as some mobster might have said.
