But it does so at the expense of those looking to borrow it productively. Wealth tax punishes hoarders without the collateral damage of preventing most from having sane mortgages.
That’s one side of the equation, but as always there are diminishing returns. Therefore, borrowing money should be mildly discouraged as ultra low interest rates results in a huge misallocation of resources.
That said, consistent low levels of inflation have minimal impact on borrowing as the future cash paying for the loan is discounted. In effect it simply forces a minimum annual loan repayment rate.
