Building infrastructure is the most used solution in order to kick off the economies again.
I don’t think that building infrastructures is appropriate now because there are shortage in budgets so the more buildings the more expenses and this cannot be afford by the dropping economy
However, this would happen by printing more money in order to drop it to the economies.
Printing money is never a good action because this will only bring down more the economy and that is what happening in other falling countries now.
It is very risky to do so as it will create inflationary trends which would be damaging to the economy instead of helping it.
At least you have already answer your own advice mate.
