The rich class and them not being taxed on assets actually play a major role in inflation too, therefore disadvantaging everyone else while they keep getting richer and paying nothing back. Elon musk was able to buy Twitter by getting a loan based on his stocks. Jeff Bezos, Mark Zuckerberg and so many more of the billionaires never pay any tax or pay very miniscule tax because so far unrealized gains were not taxed.
In the USA it was considered radical to tax unrealized gains, but it's actually a common sense measure. The more Trump tries to push back on it the more votes he will lose, because more and more people are having a harder time surviving now while the rich class pays no tax so far... It's ridiculous to try and defend this from Trump's side and unless he also comes up with some equally popular measures I'm certain he will lose the election.
