Why does wanting more imply having people underneath you?
Your comment is full of frustration, hatred and anger, it doesn't have any argument in it. I hope you can see that.
The main issue stems from the fact that Europeans have a different lifestyle, therefore, moving forward for them implies having actually higher wages, not lower ones, in order to have at the end of the month some free days of vacation, health insurance for the family, etc etc.
The comment you are answering to says exactly that. It didn't mention anything like "let's send them back" or whatever it is, as you seem to imply with your words. It was an honest observation (backed up by economists, by the way, just google that) about the fact that by giving more work to people who get less money won't do anything else than lowering the salaries for the entire sector. Of course, it will give people from other countries a possibility to work and make it, however, as a local citizen wishing to improve my country and the average income, why would I care about people coming from other countries? I mean, what do I get in return?
