This comes directly from a historical British restriction on voting rights that in turn is an artifact of feudalism. https://press-pubs.uchicago.edu/founders/documents/a1_2_1s3....
Ancient democracies, including those of Greek city states like Athens, restricted voting to landowners because prior to the invention of the printing press, only aristocrats could understand the issues being voted on.
Eh, a growing set of cranks. The diversity of political opinion in America seems to have exploded over the last decade. Cranks are now serious contenders for power and influence.
This is such bullshit. Pre-literate societies were not ignorant societies, they were not stupid societies, they were not issue-free societies. The printing press gave rise to literacy which then gave rise to both books and print-based issue campaigning. But the idea that before people were able to read they were also unable to understand "the issues being voted on" is ridiculous. People ate, built, got sick, got hot, got cold, got injured, were richer or poorer ... everyone had a framework in which to understand "the issues being voted on".
You could argue it wasn't an educated understanding, and that might be correct depending on your understanding of what "education" is. But the idea that people couldn't actually understand stuff until literacy arrived is just ridiculous.
So are the justifications of Adams and Blackstone. Literacy was the justification given by early Greek democracies with written legal codes, though some, like Athens, later broadened eligibility.
Someone renting an apartment and working a job in a community definitely has skin in the game in regards to local tax rates, building regulations, public amenities, etc.
Everyone has skin in the game but some have way more.
Maybe those transient homeowners are the ones who shouldn't get to vote...
Obviously someone with a kid enrolled in school and locked into a long-term lease is not transient and has a comparable amount of skin in the game as a homeowner.
(I still disagree with your broader point, since I don't think you can meaningfully draw a "has skin in the game" line.)
Not serious debate.
