Harris is pragmatic, Trump is living in an imaginary world in his mind. For example Trump claims the US will “earn” trillions by taxing imports (tariffs). That action will directly tax US citizens as it ends up as an expense added to your sales price. Ok Trump is delusional or ignorant.
Where Trump also promoted more tax breaks for billionaires, Harris plans to increase tax on that group and use it to strengthen US economics with programs for small business and lowering the cost of housing. By the way those older tax cuts to billionaires by Trump went to fund billionaires buying up monopoly positions in housing so they could jack up prices to become richer still, more powerful.
