The only thing the sufficiently rich can't call-and-raise you on is time. Fictional sums of money, sums that may be less than likely to ever really be paid, are more easily reckoned with than jail time.

Stealing is also an economic crime then, as they are stealing it because they cannot financially afford it and no one should go to jail but only pay a fine.

Of course not, the reason might be economic but the crime is against much more than the economy and the punishment should be even greater still. Fines do not even register.
