If you're looking to hire someone for less than that... hire an American!
There are plenty of people who have no desire to live in places with that high of a cost of living.
* Age
* Language skills (English and French, measured via standardized exams)
* Level of education
* Level of education and/or job experience in Canada
* Job offer
* Desired destination to live in (easier to move if you want to go somewhere underpopulated)
* Personal savings to prevent you becoming a burden
If you get enough points, they invite you to obtain Canadian permanent residency. If you don't, you can still get a work visa, work for a while, and re-apply later. Compared to the US immigration system, it's freakishly straightforward and reasonable.
New Zealand is even simpler: they'll just start your residency process based on the mere existence of a job offer and a few checkboxes regarding age, language, and education. They've got a whole "Move to New Zealand" website now, with pretty pictures, clear instructions, and government webpages bragging about their high quality-of-life.
It really leaves one thinking, wow, this is what a First World country acts like.
Raising the minimum wage to 100K is the wrong approach. Computer science degree programs are a major source of development talent for many organizations, and I doubt most companies will be willing to pay 100K for jr developers graduating out of Master's program. This will start a weird loop were US higher education will no longer be attractive and talent pools will dwindle with universities suffering from major revenue shortfalls. And if students start going back to their native countries after a US higher education, it just enriches the talent pool abroad making outsourcing even more compelling.
Further, there are a number of professions outside of software that employ H1B candidates to perform important roles - mechanical engineers, industrial engineers, earthquake analysts etc Those fields have even more shortage of talent and a minimum 100K wage will further shrink the talent pool.
