It can be said that the very wealthy have a very different relationship with money than others, and in part, this comes about when you can live on say, less than 10% of your net income. The very wealthy live on a fraction of 1% of their net income. They see money as a means to make more money, that is, investing in assets and minimizing/eliminating liabilities. It's simple business acumen that can be applied to their lives. One of the reasons why you can't "tax the rich" is because they put everything they can into the business, the cars, the houses, the yachts, the artwork, etc. On paper, they don't own things, and you can't sue them personally, but rather you have to go after the business. They invest heavily and they can only be taxed on that if they sell those stocks for a profit (capital gains), like Elon Musk a few years ago when he sold stock and had to pay $10,000,000 in taxes. That's our tax code, and I don't think the wealthy decision-makers are going to change that in order for them to "pay their fair share".
Now, having said that, this very same tax code applies to the rest of us "poor schmucks". If you are an entrepreneur, then you can apply many of these strategies. If you are an hourly or salaried worker, it becomes more difficult because you don't have the opportunities for tax write offs. Some of us live on 90% or more of our net income, where simple living expenses become overwhelming.
Do many of us spend money on a ton of crap we don't NEED but WANT? Oh, yeah. Do we spend too much on automobiles, houses, recreational vehicles, lawn tractors, big screen TVs, computers, and so on? Oh, yeah. The poor and middle classes spend almost all of their income, by necessity or by mindset or by poor self-discipline, there are many reasons for this, and this is what drives economies. Can you get yourself out of financial holes? Many times, you can, but it is going to be painful. Can you make the right investments on your investment apps, like Robinhood and the like? Yes, you can. Doing it right now. Everything has risk, and you have to be OK with that risk, which is a mindset that you must have in order to invest.
