How can I, as an individual, exploit the same tax havens mega-corps use to pay no US taxes? What is the actual financial cutoff/rule that allows corporations to pay nothing, while me to pay ~40% in aggregate taxes. | [
"One way is to 'buy a part'. If your a rug dealer and you made 100,000 in profit last year selling rugs you will need to pay that in taxes. To get around this buy a 90,000 golden magic needle from Iran, now you only made 10,000 in profit. The company in Iran (which you also own) now has to pay licensing fees to a c... | [
"Legal Tax Avoidance, to distinguish from things like just not paying, is not easy to do. It requires a degree of financial knowledge, wealth, and connections to achieve. The average person may not know how to set up a tax haven, or move money through companies to avoid paying income tax. The wealthy can afford to ... | eli5_question_answer | {

Why is it that after you say or type a word many times in a row, you'll begin to question yourself as to whether it's correct | [
"It's called [Semantic satiation](_URL_0_). Quoting wikipedia: > The explanation for the phenomenon was that verbal repetition repeatedly aroused a specific neural pattern in the cortex which corresponds to the meaning of the word. Rapid repetition causes both the peripheral sensorimotor activity and the central ne... | [
"When you know a word and hear a word, it's easier to remember what that word means. But it's often hard to think of a word when you know the meaning.

Why do people use AskReddit and eli5 subreddits when Google can usually answer their question? | [

Why does Apple iOS8 require 5.8 GB of space to be downloaded? | [
"Because the entire operating system must be downloaded before implemented. If it wasnt there would be no os to finish the download. Once the download is complete the os writes and is no longer taking up hd space, besides most of what the old os took up itself."

Why do cops who abuse their powers get 'punished' with paid leave? | [
"Most of the time paid leave is for when there hasn't been an official ruling/conviction yet, but they don't want the person running around with a gun and a badge either. So, it's kind of the period between when a cop is believed to have done something, and the \"conviction\" in some cases."
] | [
"Because they aren't. The overwhelming majority of cops never fire their weapons throughout their entire careers. You only hear about corrupt cops in the first place because they are out of the ordinary. With that said, when a corrupt cop *is* exposed I want them punished and harshly."

Why are contests in Canada always open to "legal residents of Canada (excluding Quebec)"? | [
"Quebec has a bunch of policies about sweepstakes that the rest of Canada does not. Rather than spending a bunch of money to make sure all the rules are followed, companies prefer to just not run the contest in Quebec."

Why is there 360 degrees in a circle, not something like 500? | [
"There are 360 degrees in a circle because the Assyrians were the first ones to do geometry and write it down. The used the base-6 (senary) system.

If I buy something from a store that's supposed to support a cause, how does it work? Are poor children actually getting a pair of shoes if I buy a pair myself? | [
"Ask the store. It could be anything from \"1% of the profits we make (after recuperating cost) to \"We buy from independent makers from poorer countries, and then sell on to you\". The range is massive."

"Unless stated specifically when you buy it that profits go to some cause, the profits go to the person or company selling the bumper sticker. It's no different if you buy a shirt with an American flag on it from Walmart, Walmart has no intention of giving away the profits."

Seriously, what's the actual go with the crappy "I make this much in a week", "Hot chicks in your area", and other assorted ads. What type of people are making them, what are they actually trying to achieve, and does anybody really take them at face value? | [
"As a rule, scammy things target stupid people. They don't want smart people to respond because smart people are more likely to realise what's going on and cause trouble. So they deliberately make these dead-obvious ads/emails so that only the dense apply."

"They don't have an interest in following you, they're either ways of getting you to go to some site (like the latter group) or they're people who follow you in hopes you'll follow them so they can up their number of followers... for some reason this is valuable to people."

why were zeppelins ever used in warzones in WW1? Weren't they really easy to shoot down, killing everyone on board? | [
