A hell of a lot of construction workers around here don't speak English, and there's no shortage of them.

I don't know what jobs pay actual minimum wage any more, especially for adults. Only about three percent of hourly employees get Federal minimum wage or less, but that number is a year or so old, and I don't know what it will be after the recent increases.

Most states, especially populous ones, have their own minimum wages that are higher, and an accurate assessment would have to take into account state minimums, not just Federal. When the Federal rate goes up to $7.25, the map I linked to will change some. You can see if you scroll down that state minimums are climbing in response to the Federal one. All wages are driven higher by the minimum wage, even if they were higher to begin with.
