Well what happens is, lower taxes means multiple things, such as ensuring the money is actually spent in the economy, buying food, goods, services instead of centrally stored in the treasury where it stays for a long time until it's being used for big projects that only a few big corporations have a use for. You're able to provide most government services with basic taxes, especially when the economy is supported by a strong middle class. Third world countries may have low taxes, but it only benefits the top 1% (or less) because they don't have a middle class, serving only as safe havens for huge corporations.
Your money can go much further when you're able to spend it for your own goals, the more money you saved up the bigger investments you can make. This also results in economic growth, which can lead to more jobs, meaning less people dependant on government. In time, as its a process, you'll find that, combined with the other things I mentioned, come out much stronger than continuing the way things go now.
At this point most (new) taxes are redistribution of wealth, which especially with big bureaucratic government causes most of the redistributed wealth spent off-shore or only to a select few (such as special providers of food and services for the royal families in the middle ages)
That's my view on it at least.
