There are many factors at play in why you have to wait so long to see your doctor -- it has much to do with changing expectations and can't all be ascribed to immigration. Fewer medical students are opting for family practice; more people go to the doctor for minor complaints such as common colds or sore wrists from keyboarding too much; more people demand specialized tests requiring requisitions and referrals; more workplaces demand doctor's notes to justify absenteeism, etc., etc. It would be the same if all those immigrants were white, English-speaking people from England. It would be the same if we had no immigration at all.
