Trade union control also spread to small businesses of the middle class handicraft men and tradesmen. In Barcelona, the CNT collectivized the sale of fish and eggs, slaughterhouses, milk processing and the fruit and vegetable markets, suppressing all dealers and sellers that were not part of the collective. Many retailers joined the collectives but others refused, wanting higher wages than the workers. Throughout the region, the CNT committees replaced the middle class distributors and traders in many businesses including retailers and wholesalers, hotel, café, and bar owners, opticians and doctors, barbers and bakers. Though the CNT tried to persuade the members of the middle class and small bourgeoisie to join the revolution, they were generally unwelcoming to the revolutionary changes wanting more than just expropriation of their businesses under force or threat of force and a worker's wage.
