Nobody says "let's tax the corner baker", but often will advocate for tax policies that would negatively impact that baker in the name of taxing the "rich".

IDK how is it in the US, but where I live, additional regulations are more of a burden than taxation per se, and compliance with new regulations is usually easier for established big players than for the corner bakers.

This is true in the US too, but reducing taxation is easier than reducing regulation. That said the same rings true for regulation as it is predominately a weapon used by the left

the corner baker is a llc last I checked

Meaning? You do realize corporate taxes are also marginal, yes?

Marginal for you, but not for the baker. Unless you too think 21%(+ about 9% in Cali) isn’t marginal. That doesn’t include all the misc taxes which push your overall rate of doing business closer to 50%. That’s just the llc(baker) rate
