Depressed labor wages:
--Unfettered illegal immigration hurts the poorest people. It also makes a class of people with less rights than citizens which is very bad for everyone. Look at what happened to the wage in the meat packing industry when they switched to using mostly illegal aliens as labor. This is of course illegal but both the Democrats and Republicans for their own perverted purposes continue to write laws that they actively don't want the Executive branch to enforce. Trump has tried to undo some of Obama's executive orders by not renewing them and he keeps getting taken to court because he didn't renew the illegal executive order that circumvented actual law????
--Exporting manufacturing hurts the poorest people and it decimates areas that loose the jobs. Not only the employees of the outsourced company but all the retail, the tax base, etc. We can't stop companies from offshoring production but we can certainly make it more expensive for them by eliminating their tax breaks. The companies should loose their American "citizenship" as well and be treated for tax and regulation purposes as foreign companies. Giving companies tax breaks for moving their operations offshore simply boggles the mind.
--Importing cheap foreign workers on the h1b visa program hurts the high paid American workers they displace. I have friends who were victims of this the day 8 busloads of Indian programmers arrived and the entire IT department was ushered into the auditorium where they were told to train their replacements or get NO severance package. The h1b law specifically prohibits replacing American workers with imported workers who are always paid much less. However, the loophole is that the company doesn't technically employ the visa holders. They "outsource" to another company who employs the visa holders and they never hire American workers (too expensive) so they can't be accused of replacing them. Disney is the last big company that made the news when they did this a few years ago but there are lots of them.
Executive pay:
Government can't tell companies what they should pay their executives but they can add some rationality by not allowing wages, benefits, bonus' above a certain level to be deductions from earnings. So, pick a number 40 or 50 is probably reasonable. Any executive remuneration that exceeds 50 times the pay for the lowest paid worker, cannot be deducted as a business expense. So if your lowest paid worker earns $20,000 per year, your highest earns a million. Companies can pay what ever they want. They just can't deduct it as an expense beyond the 50 times the low wage number.
