> Aside from the obvious frontline support, artist, junior coder etc, a whole bunch of white collar "pay me for advice on X" jobs (dietician, financial advice, tax agent, etc), where the advice follows set patterns only mildly tailored for the recipient, seem to be severely at risk.

These examples aren't wrong but you might be overstating their impact on the economy as a whole.

E.g. the overwhelming majority of people do not pay solely for tax advice, or have a dietician, etc. Corporations already crippled their customer support so there's no remaining damage to be dealt.

Your tax example won't move the needle on people who pay to have their taxes done in their entirety.
