This is basically what happened in Orbán's 16 years in Hungary. He gave indirect tax cuts for the rich, or just generally everyone who is not living pay check to pay check (by hungarian standards it means you are rich). So for example installing solar panels came with a tax writeoff but the whole thing was setup that it only benefit who already have had enough money to install a full brand new solar panel system. So it didn't help at all those who are really in need. Same happened with EV cars. If you already have money for a brand new EV car you got it cheaper. For the rest? Good luck. Mind you this is eastern Europe where everyone is driving +15 year old diesels from Germany. The rich got richer.
