Under "Forces Goal 2030" I am sure this ratio will be Zero!!
I think, you are talking about the role of a true Opposition party in the Parliament. You are right that there is only one-sided view in the decision making process without the presence of an effective Parliamentary opposition. However, we have seen how the BNP itself performed in its two terms. There was virtually almost no building of physical infrastructure in those years. Not a one mW of power was added at that time, for example. So, little was added to the national debts in those two terms.When you have no opposition to debate bills, you'll find that things move far more smoothly. Unsurprising.
When the present BNP leaders do not know the importance of spending money, even with borrowed money when necessary, to build physical infrastructure, such as roads, railway lines and expressway, I wonder what role they could have played in the Parliament except to call strikes time to time.
