Yes and no.
Is your labor truly the equivalent of their labor? The depends on the perspective of the buyer.
There are also some other issues - like environmental standards, regulations, taxes, etc.
In a perfect world, you wouldn't have those differences, or people would properly value the differences. Unfortunately that doesn't happen so the closest we have is tariffs, which are imperfect.
It's funny - mathematically speaking, it's impossible to have a trade deficit, and yet there's a very real one. It all comes down to capital flows, and essentially investing in dollar denominated assets and debt is far more attractive than purchasing our exports. Our strong dollar helps drive cheap imports, and low interest rates, but it kills exports and is the result of us being owned by/owing investors abroad. Not to go too far on a tangent, but trade deficits track government budget deficits.
But back to your original statement...is your time really worth $40/hour? Perhaps to you it is, but the only way to determine whether it is accurate is if others are willing to pay that much for your time. Maybe it's more, maybe it's less...and perhaps it makes a difference as to what service you are providing for that time.
