It has a snowball effect. If you have to pay the janitor 10.10, then you now have to increase other employees pay...since the secretary was making 10/hr, now you have to bump up her pay to 13. Now the IT assistant who was making 13, will now expect a pay increase as well. And so on and so on up the line. It's not just bringing up the bottom...all boats have to rise as a consequence. You're looking at cutting at least 1/3, and saddling the remaining employees to pick up the slack. So congrats on the pay increase, and hope it doesn't lower morale that it cost some of your peers their job.
I would add something to this...
People that were making minimum wage of $7.25 and got their pay increased to $10.10 will not have their situation improved much, if any. Even if they do, it will not last for long, since they are still at the bottom of the ladder.
Example.
Poverty line for family of 4 is $23,850. If someone is making minimum wage of $7.25 and work 2000 hrs a year (50 wks/40 hrs), total income is $14,500 a year, well below poverty level. With increase in pay to $10.10, with working the same number of hours, the new total income is $20,200, still below poverty line.
That family will still receive government assistance such as food stamps, SSI, Medicaid, but since difference between two MW incomes is $5,700, that's about how much government will have to pay less in assistance and get more in SS and Medicare taxes.
Increase in MW will not help those people much, will increase their risk of losing jobs and only side that benefit is government itself. There is an old saying, dog doesn't bark to warn the village...
