Aloha! Good observation! Thank you for responding in the manner you did. This is true and I was hoping someone would take that issue and think about it. That is why I mentioned in my post that the 18% goes to "government". Government is the most corrupt entity to receive tax monies.
I will just examine the "infrastructure" issue you refer to. In the real world if you bother to follow the money these construction projects are called "Public Works". Public works is based on an antiquated law from 1934 invented during the FDR days. The law I refer to is the Davis Bacon Act. This act is the basis of union controlled labor rates called "prevailing wages". These are the same unions backing Bernie Sanders. I almost typed Bernie Madoff, but same difference. Unions are as corrupt as banks. The idea that Bernie brags about being backed by unions instead of Hillary's banks is sadly overlooked.
I speak from experience as for 25 years I was intimately tied to Public Works projects in California. Trade Unions set the wage rates on all Public Works projects where federal/state/county/city funding is required. Current total wage rate for a GED educated Laborer Class II is $93,000 per year, for the county of Oahu in the city of Honolulu, but go ahead and look up the rates for your county, they vary, but they vary at extreme rates for a GED educated ditch digger/broom handler. How much training do you have to have? Very generous benefits are included even vacation pay and medical and pension. In the 1990s I used to have all my payroll "certified" by the union. It's as if the Union had IRS powers to audit.
Is that an efficient rate for the labor duties performed? Or could you hire two laborers for the same price?
Now go down to the union hall and try to apply. The original legislation in FDR days was also a deterrent for blacks to join the union. So in the "Burn Speak" of today unions are some bigot and racist institutes. In my 25 years in the Public Works and union trades I saw about five blacks working on my projects. That's one every five years! These are the backers of Bernie's campaign.
In other words handing money over to any government has always been about total lack of efficiency and fairness. It is never what you know or how skilled you are it is always "who" you know. Being in the IBEW end of the trade unions I never saw anyone get in who did not know someone in the union and many times it was a generational issue. Government is always corrupt.
Our highly successful non-union company was always lobbied on all our projects by Union reps until they made us an offer we could not refuse. All the company execs got paid $80,000 each if we became a union contractor for a one year period minimum. We were taking so many Public Works projects from the union contractors that the union was forced to bribe us. We had such an issue finding qualified apprentices that we decided to go with it and see how it was biding as a union contractor. In one word once we were in we were "lied" to. The Union did not keep many of their promises and threatened legal action if we wanted out of our contract. We decided to quit bidding for a year to meet our contract time and went on a year vacation. We came back as non-union contractors and resumed out bidding union contractors and it became our most lucrative era. But … that's your 18% at work and to be precise many Munis and States had to float huge bond issues because 18% wasn't enough.
I have only covered half of the infamous costs, "labor". The "material" side is just as corrupt. This is where huge global corporations buy favors to get their products specified through architects and engineers. I assisted engineers and manufacturers by putting together bid estimates for preferential treatment.
Now add up all the tax dollars lost to this inefficiency and corruption from 1934 to now. There is nothing "free market" about government. The US government has added TRILLIONS of wasted taxes and debt onto American taxpayers to sway corrupt unions and keep intact antiquated FDR labor laws from the 1930s. Your kids kids will still be paying for these over priced union controlled projects. FEEL THE BURN!
I can vouch for all my bids on these projects and everything was competitive except the "labor and material" line items in my bids. Every job walk we did there was a union rep there to remind and reprimand any contractor present to obey "prevailing wage" rates. To me that was total government sponsored intrusion into free market capitalism!
Next time you are on a freeway and there is road construction ask yourself how much each guy you see is getting paid. Then when you are in an airport watch the union guys at work. Maybe a journeyman electrician is hanging a light fixture … think $120,000 for that guy! Remember Halliburton and the $200 toilet seat or the $20 Coke six pack? What makes you think the cement and light poles and signage on freeway construction isn't another Halliburton? I can say I marked up both labor and material on my bids by 50%. In a corrupt system you have to do that to survive because you know you're going to run a gauntlet for the full duration of the project. In case I got audited I did not want to have a line item for "bribes"!
That's your 18% at work! It's not inflation … it's corruption! Remember those old signs along roadways back in the 1970s? YOUR TAX DOLLARS AT WORK?
