Only for those who still have jobs.
That's the part you folks forget, jobs disappear when the minimum wage increases. Sometimes the overall economy is expanding and people rise up to meet the new requirements, sometimes people fall through the cracks but the population demographics change which makes them statistically insignificant, and sometimes those jobs just go underground.
But when the minimum wage is increased, a good portion of the current group making minimum wage with either have to expand their skillset or just be out of a job. Some roles will disappear completely: full-service gas station attendants (outside of New Jersey), porters in bowling alleys, candy stripers (they were paid in the 60s and 70s), and telephone operator positions no longer exist.
That's a load of dog poo.
If there is a demand, companies will keep all the employees needed to run the business.
Do you think McDonald's will let go of so many that people refuse to wait for their burgers? No, they are going to keep the amount needed to run the business.
There is still a demand for full-service gas station attendants, it's just below the minimum wage threshold.
McDonald's will step up their already increasing automation plans if the minimum wage goes up. They might even go full robotic and self-serve.
Remember when all drinks were made by workers behind the counter? Now they just hand you a cup and you go serve yourself. Remember when they brought the food to you? Now you wait in line to order and pay, then stand around waiting for your order.
Low wage workers and their non-paying supporters are too short-sighted and that's bad position to negotiate from. Plus, 3-5 million more low-skilled workers are about to enter the workforce. That's not going to help your case of $10 an hour minimum wage.
