what can cause 'deflationary spiral'? and how can it 'lower the price of everything'?

i think i figured out liao.

-trump is only making things more expensive for avg american. theres no question on this already.
-if price somehow stablize, it is only temporary until it returns to expensive again.
-instead of doing other way, he wants to take a 'high business risk' and want to show whos the boss. HAHAHAHAHA

this is like PN vs BN scenario la,

why didnt trump retaliate with tariff for china again? no bola fight to the end like russian war? or he knows all the shit will come back to US?

yeah and theres no way they can devalue remotely to yuan level.
