I can see the value of retaining an attorney if you run a small business and have employees, labor law is a biatch. Retaining an attorney doesn't mean paying them $350/hr all the time, though. I mean, if I'm getting sued for withholding wages or for improper termination, okay then game on, I'm gonna pay for good representation, or get taken to the cleaners.
I pay an accountant a flat fee every year to oversee taxes, discuss tax strategy, etc... I have book keepers do the grunt work entry and pay like $50/mo for Quickbooks & $40/mo for payroll processing. So does my accountant make about $200/hr? Probably it averages around to that.
Devil's in the details. The clock isn't running all the time.
But yeah if you're a plain vanilla W-2 employee that works for CVS and you don't file schedule C, don't manage an LLC or S-Corp, and are not in a limited partnership or have active engagement (not passive gains/losses), and you're not actively being sued, there's pretty much zero reason to have an attorney or CPA actively working on your stuff all the time. Maybe if you have some estate planning issues you need to figure out, but it's not that hard to DIY revocable trusts and financial planning....and just pay someone a flat fee to review.
