@mc+1jp4wz64c I'll go ahead and answer your question in the spirit that you are serious. My recommendation is based on listening to hundreds of hiring managers looking to hire thousands of positions ranging from entry-level to C-suite (e.g. CEO, CFO, COO).
If you read my post carefully, my recommendation of "no tie" only applies to senior level positions when interviewing via webcam with a RECRUITER only. It's because we recruiters won't waste our time with a senior level candidate who doesn't already possess the necessary experience. Candidates wearing a tie won't impress us so they don't have to bother. If the senior level candidate is interviewing via webcam with the hiring manager or a high level professional, then WEAR a tie.
Conversely, lower level candidates don't have a lot of experience to hang their hat on (compared to higher level candidates) so dressing to impress makes a difference, no matter who the lower level candidates interview with.
As for the low pay for lower level positions, it's all about supply and demand. Frankly, there aren't many low level positions up for grabs while there are loads of lower level candidates looking for work. So companies can hire someone at the lower levels for less money. If the candidate doesn't like the pay offered, the candidate is free to decline the offer (at least in the US). The company will shed a tear and feel remorse for a second or two before moving on to the next candidate on the list to extend the offer two.
Here's a fun fact: I have NEVER had to go to the 2nd candidate on the list when it comes to extending offers. Smart candidates know that a bird in the hand is worth 2 in the bush and will ALWAYS accept an offer when presented with one.
