the extent and effort at which they create and enforce those policies is the measure of left or right in this country; not the existence of those policies because both republican and democrats say that they want those things; but when you investigate beyond the lip service you find that conservatives will give token-at-best support for the policies while leftists will support it with full vigor.

tldr: the democrats very tepid support for these things is what makes them center-right; because the party that calls itself conservative takes pride in doing this, while most democrats do it too and hope you don't notice.

longer: democrats only push for re-distributive policies (if at all) once it becomes popular and they're forced to respond; not because democrats are progressive. see biden's decades long anti-gay crusade that suddenly stopped once he needed the votes and his expansion upon trumps draconian anti-immigration policies; or clinton's establishment of anti-gay service and anti-gay marriage; and then see kamala backtrack on liberal positions like pre-k; community college, childcare, medicare expansion, etc. only the democrats very weakly seek social or economic policies of government and; for the most part; behave like republicans when it's time to put their money where their mouth is; that's why they're center-right

it sounds like you're judging these books by their cover without reading any of the material. we're on social media so it's par for the course; but your takes are going to be divorced from reality if you don't bother to go further than shallow understanding.
