Fair enough. I don't know what any of the people listed pay their employees, but once an employee is hired, they usually do have the opportunity to advance in almost any area. With those entry-level jobs, they did get their foot in the door - after that it's up to them to show an employer they were capable of more responsibility and higher pay, don't they? Most of us who started working at a young age knew we weren't likely to be paid $100,000 dollars a year to start, but it was a start.
Perhaps I grew up in a different era, but we were told to show up on time, work hard, and get extra schooling if necessary. I doubt if anyone from the companies I listed above, with the possible exception of WalMart, are paid minimum wage, and even there, their store managers earn at least $80,000 a year. Plus, WalMart has no problem with hiring entry-level people...they always have more applicants for jobs than there are openings.
I did answer your question to the best of my ability, so it's your turn to tell me what Democrats have done for the middle class as far as job opportunities are concerned - and I am excluding jobs in government, since both parties have to follow the rules in that area as far as Civil Service is concerned, as an example. Companies have to be competitive, or they don't stay in business long - government doesn't have that handicap.
