Lets put this into perspective (and stop knocking ‘the Spanish’ )
I have a friend who is very friendly with a Chinese lady who is a supervisor/area manager for a number of Chinese owned shops in our area.
Their employees are all Chinese, they must work all the hours the shops are open (over 12 hours a day). They must live in company owned premises and eat only at their employers premises. Their accommodation and food charges are taken directly from their wages. Must not go out at night, must not socialise outside their immediate circle, and must never spend a night away.
I do not know what they earn, but suspect it is considerably less than their Spanish equivalents, employed by Spaniards.
This same lady, also tells my friend that around 80% of the goods they sell are not fit for purpose, but they seldom if ever make refunds.
And incidentally, I am assured by Spanish business friends that the Chinese setting up businesses in Spain get big tax breaks, not available to any others, during their first five years of business.
