Most nations structure their taxes in such a way that they are made to pay more taxes but little did they know that taxes are actually mearnt for the poor and middle class to pay.Let's say that you are paid by the government as a middle class worker.Definitely the government has control over your funds so he taxes you first even before you get the money.The rich man who owns his business decides to delay tax payment and use that money to even make more investments and later pay or better still there are legal ways to swerve tax payment. So the rich are smarter than the government.
It's probably better not to say that the rich are are smarter than the government, but rather that the rich run the government. Rich people fund the government leaders and their campaigns. They have private meetings with politicians. They constantly lobby the government. Rich people influence politicians to have laws created that benefit them. I think your version of how the rich pay taxes is a little simplified. Of course, they can invest the money instead of paying taxes up front, but they should also be paying taxes on the capital gains too.
