What goes up...won't come down

What does the '0' means? No consumption at all? I don't understand this table. No explanation summore. And gahmen think we stupid or what... the tariff raise that affects the manufacturing sector like factories and plants, will eventually result in increased price for everything under the sun, just like what the fuel price hike did. Dare to say it won't affect the low and medium income group. Bunch of lying morons who treat us like we're stupid and 'grateful that gahmen is such a considerate and loving leaders'. Tsk tsk tsk shameless *beep beep beep*
