There is no point in arguing any of this. The remainers on this forum take a statement like

"this COULD mean that we will be poorer"

and re-interpret this to mean

"this WILL mean that we will be poorer".

but the original statement could also mean

"this COULD mean that we will NOT be poorer"

which COULD mean that we will be the same or even richer.

Three possibilities of which the inconvenient two are ignored.

Why would any intelligent person argue around this?
