+1 about overseas freelancers. And US customer to European freelancer is not the arb it used to be. The California SaaS sector has collapsed in the wake of venture capital rotating into AI-native, saas budgets (salaries) are down, the dollar is down, and remote European salaries are up. Zoom latency across 7-8h timezone difference is workable, the current arb is to hire from further and further east. Unless there is a war disruption such as an attack on the trans Atlantic internet pipes.

Are you using 'arb' to mean something like cheat or trick, or cost-saving technique?
