Living in a country inside as a (white) individual is mostly beneficial as others mentioned already. One problem lies in the structural component: The EU is rooted in highly liberal (in the political sense) values regarding market and trade and NOT in the collective or common of the european people.

Enforcing the former leads to loads of economic problems, for example Germany being the major exporting country which contributes heavily to wage dumping. That export surplus prevents other states like Italy or Greece from regenerating their economy and keeps them low as their options of controlling imports (e. g. Through tariffs) are limited or not allowed, thus further cementing disparities between countries. Besides, there is a rising tide of far right movements in the EU happening which might be related to the economic instability and insecurity a heavy market liberalisation brings.
