Hypothetical question:If someone had a plan to help the poor and low income and it would only add 9 trillion to the deficit think it would be looked at?

I am guessing the conservatives would cover their ears and scream the sky is falling.
But those same conservatives are going to extend those tax breaks from Trump’s first term which will add 9 trillion to the deficit and none of them will have a problem getting that passed.
The real question why no problem with the wealthy , but a big problem with the lower classes ?
