" Faced with protecting people or protecting their profits, too many go for the profit"
That is why the legislation is in place covering all aspects of life.
But it is also a one size fits all approach. Some are allowed to be killed/injured in order that the majority benefit. Vaccinations are a case in point. A very small minority suffer adverse effects. Similarly if you want a first class defence force accidents will inevitably happen, causing casualties.
The idea of a bonfire of regulations is a cheap totally impractical soundbite. The flak from mass casualties resulting from such a rollback would totally destroy the party responsible. That is not to say that a close re evaluation of legislation is not desirable. How often is legislation repealed rather than added to?
You are creating a remainer myth based on fantasy.
