I think you’ll find you have got that a little wrong there, the huge flaw in your theory is that somebody else owns the truck you drive, he pays the finance, maintenance, taxes etc, pays your wages and employers contributions on top of all that and still makes a profit out of the deal.
Those owner operators are doing the same job as you and they will be earning twice as much as you after taxes, they will also have paid for a truck that will have a value that when added to the equation will, with the right truck, take their earnings up to around three times what you get for doing the same job
