We are really focused on providing this as an "on-ramp" for small employers. Providing large employers an "off-ramp" isn't a use case we have seen much interest in. However, there is an interesting historical precedent with retirement plans, which suggests that there can be systemic benefits that come when employees have more control. Pre 1978, employers offered pensions as a retirement benefit, and like health insurance today, they were selected and managed by an employer — and all kinds of bad behavior resulted in this misalignment of the buyer and the beneficiary. 401(k)s were the consumer-driven answer to this, allowing companies to offer tax-free funds that the employee could manage themselves. Since 401(k)s were easier for employers, the number of businesses offering retirement benefits grew significantly, and the number of employees reaping the tax benefits grew as well.
