To compare Trump and Biden, you'd first have to find some common denominator, a basis from which to make the comparison. Since Biden has never had a job outside of govt, nor started a company, nor made a payroll, it's kind of hard to make that comparison.
I think we both may mean the same thing when we say "system", so at least we can agree on that Difference being, Sundowner Joe sucks money from the system and gives nothing in return.
Alternatively, Trump constructs buildings, renovates old buildings, gives people jobs, pays employees' wages, pays their employer taxes, provides them benefits like health care (I know you'll like that one!), collects their employee taxes for the govt, etc.
If in the process, he used the perfectly legal tax laws that Biden helped create over his 47 wasted years in govt, for things like tax credits, asset depreciation, etc., then all that proves is that Trump is smarter than Sundowner Joe. (just ask him! 😜🤣)
