Nope. Were talking manual labor jobs not clean jobs. Right now you can make a very good living doing the dirty jobs but few opt for that. They want clean, 9-5.
Who is “they”? If you offer pay of $100.00/hr to do welding you will getting 10,000 applications. If you offer $6.00/hr you will get zero applications. The trick is to find the price point between $6.00 and $100.00 per hour where you get the right kind of applicants with the right experience level. It is all supply and demand.
