And now all the "small jobs" that would have been paid under that amount disappear.
Life isn't always fair, you need sacrifice somethings to achieve greater things. So what you're trying to say is the minimum wage would had stay that way so there'll be more smaller jobs and get paid in such a small amount that can't even last a family for a month?
That is how freedom (in economy) works, but it results in the opposite of what you think...
The people who get those jobs are not planning to make a career from them (at least most won't). But what socialism wants is to end those jobs (by force), so it results in zero income vs poor income to the group who was benefiting from them.
If you leave those low wage jobs alone, some people will have a starting point where to move from. You do not stop looking for better jobs when you start a low paid work. And as an employer, the higher wages socialism orders you to pay, the less job offers you are going to give, and with more socialist "squeezing"; the business itself simply closes or goes "family" oriented (which is a variant of informal or grayish).
Your socialist move to "improve" workers salaries by force of decree, will produce in the end, a reduction in workers salaries. This is the main problem with trying to apply socialist mentality to the economy. The same results when you impose a "lower price" to goods.
Another example is when you want to "protect" jobs by it making hard to fire people, then less employers will want to employ, because it becomes too expensive. Every tiny little thing you add to the law "in the name of workers" benefit results in less jobs, and also in less employment.
So how to actually solve this? You go in the opposite direction. By promoting a free economy, you get lots of job offers, since its cheap to hire and easy to fire, you get more jobs available in the market. And that leads to... Competition, which leads to.. better job offers (with better conditions).
Another way to stimulate the economy would be to lower taxes, yes, lower taxes. That stimulates people to open more business, and the State ends collecting more taxes. Ironic isn't? Economy tends to work the opposite way socialists think. This is because socialism tries to "fix" the economy by force of what can actually be solved by choice of freedom.
From a worker's perspective, he/she wants to have access to those low paid jobs. It is their choice to do them or not. This is a choice you are removing by raising wages. And yes, it fuels the "black market" (as in illegal, mind you). Its the very same thing that happens if price of things are fixed, when you foolishly try to "stop inflation" by decree as they did in Zimbabwe under Mugabe or Venezuela under Maduro, and ignore the real problem which is you overspending and then trying to fix the budget by "printing" money to pay for it, leading to more inflation, etc.
So there is nothing to celebrate, and lot to mourn. Venezuelans are currently earning $8 a month. See yourselves in the mirror before its too late...
