The government doesn't generally tax poor people much, so most tax savings benefit those that can better afford life already. The whole purpose of taxes is to take enough from the ones that are still doing okay and redistribute it to stuff that more wealthy people wouldn't necessarily choose to spend it on, but that are still a net benefit to society over other causes.
So, say government increases the income limit for one of the lower tax brackets by $5,000. That's great for people who make more than that, which btw isn't all poor people, but at the same time it also gives more money to everyone who was already doing okay. Meaning inflation will soon eat up the extra money and we're right back where we started.
In order to help the poor with upgrading to non-poor, the government has to explicitly avoid extending that benefit to the rest of society, has to continue taking from middle and upper income people. It needs to be targeted, and tax cuts are a great way to target middle/upper classes while helping poor people less.
