United States Politics: ∆τ_i*ε*φ*m_i<0 where ε=4 and φ=0.25

Trump's policies are going to put upwards pressure on prices and inflation. I'd be getting prepared for interest rates to stay higher for longer and for high inflation to stick around for a long while. Hope no one was planning on retiring early, your savings are about to be eroded.

Which policies are going to do that and why did this not happen the last time he was in office?
