How many people can be on the edge of a dime?

Although I am thoroughly disgusted with the GOP and their remaking themselves the Tea Party, when it comes to the budget deficit and the need to get it balanced, both sides are at fault. GOP, taxes are too low, no if, ands or, buts. While the norm for the amount of government income (taxes) to GDP and expenditures to GDP is around 19%, and taxes sit at 16% now. This cannot continue, and taxes must be raised. But expenditures are now at 23% or more (it seems to differ by how it is calculated), and this cannot be continued. So my suggestion is to have taxes at 21% and expenditures capped at 19% until the budget is balanced, and the then taxes can be lowered to 20%, and expenditures can be raised to 20%. But I know that will never happen. Why? Because in a lot of ways, it is like I am on the edge of a dime, seeing the head side and the tail side never meeting, and thinking they are both the only correct side to the coin. But until there are more people not siding with either side of the coin, but splitting the difference, there won't be any compromise. And that makes me wonder, how many people can fit on the edge of dime, anyway?
