Tax cuts are tax relief. When you get a refund it is not a hand out from the government, it is YOUR money being returned because you paid too much. The government runs on your money. It takes from you for the 'common good'... and some of that common good is waste (pork).
You might have a valid point, but without any actual numbers, you're just parroting ideology.
It's entirely possible that 60% of spending is pork, but the 40% that goes to the common good is so valuable that it is worth wasting 60 cents on the dollar.
To actually have a point, you need to show that the common good generated from your tax dollars is not worth the extra pork that goes along with it.
TLDR: I don't take it as a given that your ideological preconceptions are correct.
