The only thing that could make commodities go down again is when it got intervened, but then again you shouldn't expect too much, always be prepared for the worst that is by keep trying to increase your incomes.
with how things are panning these days, much better to secure yourself to be self-sufficient. with the rising prices, one person can't beat such scenario. but you can help yourself in your own little ways. if you have small lot of land or even a vacant terrace, start thinking of how to grow some of your veggies. it won't take too much if you think about it. small effort and you won't be worried buying some stables from the market.
what i wanted to convey here is that we should not rely from our government or anyone else to see some changes. we can start on our own self how we can address such dilemma of rising prices.
