Rather, you're leveling it by expanding the labor pool to include the rest of the world, aka via globalization. Not inherently bad imo, but I could understand why someone patriotic would find this problematic.
The alternative to fewer H1B visas is not just hiring Americans. In fact, hiring Americans is far less likely than simply hiring Indians and letting them work in India. Or, as is happening increasingly, having Chinese and Indian employees who were educated in the US, move to Canada.
Semantics. In economic terms, it's expanding the labour pool.
You could also just directly apply to a position that happens to be in Canada, e.g. https://careers.google.com/locations/toronto/?hl=en
By the way, you actually might not need any FAANG (or other Canadian employer) help: https://www.canada.ca/en/immigration-refugees-citizenship/se...
Most businesses are at equilibrium. There is no choice of "hire locally and pay them well or hire globally and pocket the difference". The choice is "hire globally and expand" (and eventually hire more locals), or "hire locally and stay small, or even get out of business".
