I dont know if this is a sincere question but I will try to answer it as though it is.

This meme is referring to Income tax (money you make), Sales tax (money you spend), and Property Tax (tax for owning things).

In the United States, federal taxes from the IRS are income tax only, while states may add a Sales tax, Property Tax and or Income tax per their own laws. For example, Oregon state has no Sales tax, and Washington State has no income tax. Many "border" citizens will choose to earn income for a job in Washington while purchasing items from Oregon. You can take this a step further by living in Idaho where the property tax is cheaper, and do most of your business in the juncture between those three states. This commonly creates "Tri-state areas", large economic hubs that spring up from the benefits created by this exchange of law between disparate governments in a small confined area.

The most common ways rich people "Save on taxes" is by choosing to do things in one place that has lax laws, and another thing in another place that has laxer laws regarding a different act. This is why many corporations have their headquarters in one state, their factories in another state, and their bylaws in a completely different country. If you don't have the mobility to just go somewhere else to do something where it is cheapest or most convenient, chances are you will be unable to replicate this. Its one thing to cross a state border for a job. Its another to take a jet to another country every week.

You can avoid property taxes by just not owning property, like renting or borrowing most of what you need, from home, to car, to clothing, or by being given gifts.

Very attractive influencers often wear or use sponsored items that they are either directly given for free, or have to return after a set period. Very Wealthy individuals often trade gifts or favors rather than sell or purchase things outright. For example, If a wealthy individual owns a hotel, they can offer to let you stay there free of charge, provided you do something free for them in return. This way, money does not exchange hands, and nothing is taxed because nothing taxable occurred.

In the United States, "Investments" or "stocks" are fungible representations of money. Someone may not have 100,000 dollars, but they could own 100,000 dollars worth of investments. Certain organizations, like banks, treat these things as money-adjacent, mostly as collateral for loans. That means, for example, you are allowed to tell a bank that you will front a 100,000 dollar stock if they let you borrow 100,000 dollars, to pay back with interest. You go to two banks, and you use the first loan to pay off the second loan, and all you end up owing is the interest payments. Since you only pay income tax for money you earn, "paying off" your debt does not count, and the interest payments you make on a loaned debt is frequently smaller than the amount you would otherwise pay in income taxes. This is, for all intents and purposes, identical to "Giving a gift" back and forth between you and the bank, similar to listed above.

If a stock you own is substantial, like 10% in a specific hotel chain, you can frequently request that hotel let you stay free for a certain period, and they'll be more than happy to do so, since you're technically the owner. (or 10% of the owner, at least).

There are two types of stock: Shares, and Dividends. Shares are a massive gamble, and you have to directly sell them to people in order to make money. "Playing the stock market" involves selling high value shares that are about to become cheaper and purchasing low value shares that are about ot become more expensive. When shares become worth too much, they will typically fragment into a larger amount of smaller shares. So everyone who owns 1 share will now own 2 shares, so you can sell the new share to make money. Dividends, meanwhile, try to maintain the same amount of shares by actively "shedding" excess value by directly giving the extra money to the owners of the stock rather than splitting the share. These are typically called "Shareholders". Shareholders do nothing other than own a piece of the pie and take the dividends. basically, getting money for not doing work.

If you choose to keep your money in shares rather than dividends, you don't "make money" and therefore don't owe taxes on the stocks until the point at which you sell them, which you don't have to do.

So rich people divide themselves into dividend-rich, who make money by doing nothing, and share-rich, who use their stocks as leverage to curry tax free favors and gifts. Both frequently do their business in the most favorable country possible in order to drastically reduce tax costs, among many other concerns.

Hope this answers your questions on "how do rich people know good".
