Maybe employers can stop suppressing uk wages by exploiting cheap Eastern European labour and pay a decent wage for a days work
Nice idea in theory, but doesn't work in reality, not for a nation that has foreign competition for exports, and which has just voted to cripple the service industry which the UK relies on so heavily.
Cheap european labour is generally employed in sectors that require limited skills, and as there is an abundance of limited skill workers this means payment for these will always be low. Improving wages for lower-skilled jobs, often means that wages for higher-skilled jobs also go up, as higher-skilled people will want to be paid more than lower-skilled people.
Also, these lower skilled jobs and industries can be replicated elsewhere all over the world, with ease, and for less cost, so to compete with these we need to be able to do things at the same cost, if we pay more with higher rents and bills etc, this becomes impossible.
They can, and will stop suppressing wages, for a time, but there won't be much of a gain, as it will just put costs up (which also puts up your costs for UK goods/ services also), then exports will decrease, then less jobs exist, then there's more competition from natives for jobs (due to more unemployment), so natives then just undercut each other, or sit on the dole. So nobody is better off, and the whole UK economy shrinks or does not grow as well as it could, so ends up further behind.
The market controls prices, and the prices control the wages, unless you expect people to run businesses and not make money (or not break even in the case of the UK with brexit).
We need foreign labour, to carry out the work that the low skilled brits think they're too good for, and immigration is a proven benefit to the economy. If the economy does better, then everyone should do better, if it's not the case then the problem is not the immigration, it's the taxation and wealth distribution.
