Also, social welfare systems are usually required because you tax people to a point they can’t save money.

This is a grave misconception. Taxes are not what stops people from saving money. Taxes are proportional to income, expenses, and/or wealth. No matter how little money you make, taxes will never take all of it.

Prices of goods and services are what stop people from saving money. Prices are always set as high as the market will bear. Landlords and merchants are trying to take all of your money, not just a fraction of it. This leaves no room for savings unless you make a great deal more money than the average person.

The saying does not go, “the taxes are too damn high.” The saying goes, “the rent is too damn high.” Never forget that.
