On those negatives: "higher prices" our food prices are rather high due to EU Tarrifs from none-eu countries. Food Prices can fall as the UK free to make trade deals with others. (Specific meat and Australia)

"lower employment" we have low-unemployment and a plan to reduce immigration. Employment will perhaps rise which may not be a good thing.

"lower standards for UK workers" labour opposition myth, its a good one "nasty tories". If they lower standards we elect labour in again to raise them. yey democracy
