a) those countries with most people and inhabitants proportionally get more votes in the European Parliament. But even then for many decisions each country, no matter how small has to agree or disagree with important implementations on a national level and has veto power, something the UK as you know has made plenty use of. So yes, as Germany for example has more people than the UK it gets relatively more votes through more EU parliament members than the UK. Seems very fair to me.
b) everyone benefits. First the cheap laborer who earns more than before. Then we consumers greatly benefit from unskilled labor because they are relatively cheap and hence produce relatively cheaper products so we in the end can afford that second car in the garage from our discretionary spending that is leftover because other household items are so darn cheap. Look at the US. The American consumer would be dead may years ago without cheap Chinese imports. Those cheap products kept financing the nice lifestyle of most Americans. Then the communities and country also benefit from unskilled labor because there simply are jobs that nobody else wants to touch. Garbage removal, elderly care takers, barista,.... Those jobs would remain unfilled or would earn way higher wages because of demand which in turn would make your coffee or care taker home unaffordable.
It is not as black and white as you attempt to paint the picture.

Which countries control the decision making in the EU?
Who benefits from cheap unskilled labour?
