Entry level jobs (minimum wage) are never intended to be a career. The vast majority of these jobs are a seasonal job or part time job as well, which works perfectly for students, retirees or as a 2nd job for Christmas money.

 Raising the minimum wage has consequences. Employers do cut back hours and some install self service  kiosks instead of paid employees too. (Reuters JUNE 26, 2017: "Seattle employers cut hours after latest minimum wage rise" /www.reuters.com/article/us-seattle-minimumwage-idUSKBN19H2MV and Business Insider May 16, 2016: "Self-service kiosks are replacing workers" www.businessinsider.com/self-service-kiosks-are-replacing-workers-2016-5) 

40 hours work at $9.30 an hour (CO minimum wage) is more money in hand ($372.00 a week) than 20 hours at $11.30 an hour ($186.00 a week.)

So I always say, careful what one wishes for, because they might just get their wish.
