Aren't you completing dodging the fact that the comment/s above you are pretty obviously talking about income taxes?
If you are in between (say) my salary and 400k, no amount of increase in the price of food is going to be a problem for you unless you are ludicrously bad with money. I'm not in favour of wanton taxes aimed at "the rich" as a political manoeuvre, but let's not be blinkered here.
