No - let's put realistic numbers on it. Let's say you were at 12 - went to 15 and work 30 hours a week.
You used to get $360 a week for that. Or 1440 a month. Now you get $450 a week for that. OooooWeee you've got 90 more dollars. Or 1800 a month.
Now - you buy groceries, you buy gas, you eat lunch at a fast food place every day, you purchase clothes once a month, and you also have entertainment in the form of movies at the theater. You have utilities, rent, etc.
Your groceries a week under $360 a week cost you $100 a week, focusing on breakfast and dinner. Your rent is 500 for your efficiency apartment. Your gas normally costs you 30 a week. Your utilities cost you 200 a month. Your movies costs you 40 a month. Clothing 50 a month. Your lunch 40 a week. Then Insurance for your car and Apartment are 100. Basically your spending takes up 1400 of that 1440.
Then Inflation occurs with the minimum wage increase.
Now your groceries cost $125 a week. Your gas costs $45 a week. Your lunch weekly now costs $60. Your movies go up to $60 a month. Clothing now costs $75 a month. Rent is still 500 and utilities stay consistent, insurance stays consistent. Let's add that up...
$500 groceries, $500 rent $200 utils, $100 insurance, $180 in gas, $60 in movies, $75 in clothes, $240 for lunch. A grand total of $1890 now. With your new wage - you're currently $90 in the hole each month. Which means that in order for you to live - you will have to give up some quality of your life that you enjoyed prior to the Pay Raise.
Thus - you are now left with LESS wealth than you had before and are now living a life that is less fulfilled than it was.
What I've described is what happens EVERY TIME min wages increase. I hope this helps for your understanding.
