I have just read an interesting blog that extols the virtues of hard work and frugality (see the link to the Conservative in my blog roll). This is definitely the way to build wealth. Nothing is accomplished without hard work. Salting away savings also helps you to slowly build up your net worth. Today's consumer culture leads to earnings being frittered away before they can do anything useful. The advertising industry is a cancer eating away at the heart of America and the Western world today.
So work hard, be frugal and save and you will see your wealth increase.
