You're much less likely to be able to get local talent into what amounts to indentured servitude, and local talent also is much more likely to want the real prevailing wage for their work. It's all just labor arbitrage.

Agreed.

Because there's a severe shortage of talent (willing to work for the offered prices)

Natives cost more, or, more generally speaking, they are less willing to cede ground on various dimensions (pay, hours, commute, benefits, COL, etc).

This can be framed as natives having higher standards of living, or natives being lazy, depending on who you ask.
