retard it's about incentivizing car purchases since auto sales are down by 50% across the board, and lowering the burden on small business. a massive portion of the economy relies on or requires vehicle sales. capping interest rates on credit and making car loan interest deduction allows for long term cash flow planning and creates the ability to hire more people, raise wages, or pay off existing debts sooner. this is 100% a pro small business move that happens to also benefit the non commercial consumer.
