even though someone is in the country illegally and working at a minimum wage job, at least they are contributing to our economy by paying taxes and spending the cash they earn in this country
Labor generates wealth; by Laboring for the U.S. economy, "illegal immigrants" contribute to the same; which is why they are "invited"; if Domestic workers want to out-compete Foreign workers, for Domestic jobs, then they should contribute more economically,
i.e. work more for less
("that is how you say you want the job"; "ask not what the economy can do for you, ask what you can do for the economy").
You have never actually done this, so you don't actually speak from experience.
Let's see how this actually would work. The unemployment rate is 8%. There are people working at the local Walmart for minimum wage. You don't have a job, so you go to the manager and say, "Hey, I'll work for $8.00 an hour." And he would say what? He'd tell you no. Even if they were making $12.00 an hour, he'd still tell you know. He'd tell you to go online and apply.
Okay, lets try another one. There is this guy that works as a gardener, an immigrant that has been here for three years. You find out he charges $12.00 an hour. You follow him around, to see who his customers are. You speak with them and say, hey, I'll do it for $10.00 an hour. And what do you suppose they will tell you? What they would tell you is, "oh thanks, but we are happy with him."
Supposing some did say, "Oh, sure" How much work do you suppose you will manage to get, as a percentage of his business?
How long do you suppose that will stretch before your unemployment runs out in the dead of the recession when every employed person is stretching their dollar just to be prepared for the unfortunate event that they should lose their job.
Oh, and here is the kicker. There is always potential demand at any price. Technically, if your willing to work for free, there is tons of work. The problem is, when receipts fall below costs. You can always offer to work for $5 an hour under the table if you can manage to find it, working 60-80 hours a week but the cost of food and housing is prohibitive in most areas. And as it takes time to build up such a business. Assuming you could manage to build enough business, half of that time ends up being spent just getting from one appointment to another.
Consider tutoring. It pays $18 an hour. Seems like good money, except it is a good half hour travel for a one hour session. Then comes the cost of fuel. By the time your done, your down to $10 an hour and, during the recession, there are a shit load of people sharing all the tutoring jobs and not enough work. The owner of the company isn't going to give you more if you offer to work for less. He doesn't care. It works for him at what he has set his rate at.
You are just speaking, "theoretically', having never actually done this, have you? If you have, a lot of people would sure appreciate your sharing your experience.
