Again you assume a year delay on a workers full salary before the company gets compensated. Cash flow rarely works like that.

Uber driver does what 2 weeks of work before getting paid, they also front the cost of their car and gas etc. Meanwhile users are paying as soon as the ride occurs, so uber doesn’t need an account with a full years salary for every driver somewhere at the start of the year. Get paid before the worker and the worker is in effect giving you a zero interest loan.

Now for a consultant the company may get paid after the worker but the company is rarely waiting a more than a few weeks.
