Tax cuts do not spur growth in real job creation and do not spur investment into new projects and expansion of business.
Tax cuts for the working and middle classes spur consumption and thus job creation. as opposed to corporate and high income tax reductions which you are referring to. New deal has massive investments into infrastructure, digitalisation (your cutting red tape) and support for micro medium and large businesses. You are grasping at straws.
actual forensic accounting has already proven
The same 'forensic' accounting 'proved' the same with reduction of CIP and no PIT for under 26 a few years back. Yet the reality was opposite as revenue to the cities increased. Maybe the 'economic experts' you watch on TVN24 are just PO hacks who hate PiS and Poland? Maybe you were not in Poland then to remember the same rubbish that is being spouted now.
