Quite the opposite: Socialist politicans and their media lapdogs have dishonestly convinced you that wealthy people are escaping taxes en-masse by taking out loans and that this can only be stopped by eye watering wealth taxes. They frequently use a motte and bailey confusing unrealized gains (which certainly exist in huge amounts but are also significantly fiction) with tax escape via loans collateralized by securities.
But it's not true: were there meaningful tax escape that way it could be addressed by establishing rules with conditions where taking a loan against securities can be treated as realizing gains (and adjusting cost basis accordingly). Doing so would be minimally disruptive and distorting and have relatively little legal complication (at least compared to wealth taxes!).
But the reality is that the claimed tax escape isn't happening (at least not at any significant scale) particularly in the current interest rate environment, so a reasonable policy change to address it would be a no-op.
... and to grow and maintain their political standing they specifically need to push a NON-SOLUTION because they can't campaign on something that was simply done and solved, and to retain your (highly monetizable) attention they need to rile you up against an Enemy, and certainly never address the state's addiction to wasteful spending and buying votes with tax dollars as one half of the revenue vs expenses equation.
