How many business have you successful ran. Yeah he failed in a few. He couldn't have failed too many seeing how he made billions and employed thousands.
You don't have to have a successful business to make money.
If you have money to start with, which he does, he can make tons. Here's how it works, and what he's done:
Open a business with $500,000 of his own money... get a business loan of credit....
Rent out the facilities, hire employees, etc. - pay for all merchandise on CREDIT.
When you buy merchandise for $300,000 a month and have sales of $200,000 per month, don't pay any of that off. Make the minimum payment of $30,000 a month, and pay yourself a salary of $150,000 a month.
Rinse and repeat for 2 years. Now your debt is 3 million+, but you've gotten $4 million+ salary all for yourself.
Declare bankruptcy. The 3 million in debt is wiped out as that is COMPANY debt. Your personal accumulation of $4 million + is kept since it's your PERSONAL income.
That's what he's done most of his career, along with putting his name on things and taking profits in a similar way.
The only thing that he really earned money on early in his career was real estate, which he got his initial seed money from his dad - $14 million, which he calls 'a small sum'
I wish people would actually look into Trump. Nobody who supports him does. They just go on assumptions. Trump intentionally deceives people by saying suggestive words. Like 'I got a small sum of money from my dad', How much? 'A small sum'. That's all he says, and his supporters think it's a small sum by THEIR standards - that's how he tricks people. Maybe $14 million is a small sum to a billionaire, but not to anyone else!
